2.03 Electromagnetic Spectrum- The Visible Assignment 1. A Doppler radar can see the amount of precipitation that there is in a thunderstorm. It can also see the direction of the precipitation in a thunderstorm as it moves closer or away from the radar. On srh.noaa.gov it says, “When the WSR-88D transmits a pulse of radio waves, the system keeps track of the phase of the transmitted radio waves.” Which means there are radio waves in a Doppler radar. It also uses sound waves to determine when the

Everyone loves to be tan, the way it makes you look littler and gives you a radiant appearance. We love laying out on the beach under the warm sun, soaking up rays. When summer ends and the cold weather begins, the UV index decreases and we all go back to fading white. Instead of losing their tan, 9.7 million Americans turn to indoor tanning to keep their beloved tan. Starting in the 1920s this trend became quite famously known internationally. Everyone knows how bad getting sunburnt is for you and

1- The electromagnetic spectrum is the range of all type of EM radiation. It also describes the wavelength of light. EM radiation is the radiant energy that is released by a certain electromagnetic processes and a wavelength is the distance between successive crests of a wave. 2- The different between ionising and non-ionising radiation is that ionising radiation carries energy to ionize atoms and has more energy than non-ionising. Non-ionising is found at the end of a long wavelength where as ionising

A century ago, X-rays were introduced and provided noninvasive ways to view structures in the body, such as bones. X-rays cannot view the soft tissues within the body except with contrast-enhancing agents that are injected or swallowed, even still image resolution is limited. Current x-rays systems are very hard to create and use large amounts of energy. Researchers at Massachusetts Institute of Technology (MIT) and Massachusetts General Hospital (MGH) have a new approach which could dramatically

Radiation Therapy MISS.DALYA Hana abu alrous |13/10/2016 have you ever heard of the tsunami wave that took over Florida, or the huge destruction in china caused by earth quakes. Well these are all caused by waves, do you know what waves are? Or how many different types of waves we have? And how they can cause negatively and positively on the environment? Well today you will know. Many people die because of these huge oceans that take them

Research Plan and Project Summary The research questions for this experiment are “Does the power level of a microwave affect how much bacteria is killed in ground beef?” and “Is there a way to predict how much bacteria will be killed at any level of power that is divisible by 10?”. Each power level on a microwave has certain functions. For example, 10% is for softening foods like butter or chocolate, 50% is for slow cooking, and 100% is for regular cooking or boiling. As the power level increases

What is light? It is an electromagnetic radiation that is visible to the human eye, and is responsible for the sense of sight. (slideshare, 2014) Light is part of the electromagnetic spectrum, which ranges from radio waves to gamma rays. (Andor, n.d.) The wave theory of light A Dutch astronomer, Christian Huygens, developed the wave theory of light in the late 1600s. In this theory, he thought of light as a longitudinal wave. This theory states that light is emitted in a series of waves that spread

Danby 1.2 cubic foot Nouveau Wave Microwave Oven; a convenient appliance for even the smallest kitchens Quite a few households do not own a kitchen big or spacious enough to input different kinds of appliances to make the cooking experience better. This is where the Danby 1.2 cubic foot Nouveau Wave Microwave Oven surpasses the competition. With a stylish look and minimalistic size this microwave oven provides you with the essential functions and leaves out the rest. And no need to worry if you have

and laser treatment but some of these don't use light, so I am only going to focus on the ones that use light like X-rays and laser treatment. X-rays X-rays were first discovered in late 1895 by a German physicist, W.C.Roentgen. X rays are electromagnetic waves of high energy and they contain very short wavelengths so they can pass through many materials that are non transparent to light. The X in X-rays is named after the x in mathematics which is to indicate the unknown quantity. In Roentgens

The amount of refraction a light wave experiences is expressed by the difference between the angle of refraction and the angle of incidence. The light wave traveling to the boundary at an angle of incidence of 45 degrees for example will refract towards the normal because the medium it is now travelling through ( water, glass, diamond ) is more optically dense than the first medium ( air ). Below is a diagram of a light wave approaching three boundaries at an angle of 45 degrees. The medium is different

The Refraction of Light Waves: The bending of light is known as Refraction. When light travels from a optical less dense media such as air into a dense media such as glass,light will refract/bend towards the normal line and the speed and wavelength of the light will decrease. When light travels from a optical dense media into a less optically dense media, light will refract/bend away from the normal as it exits the dense medium.The speed and wavelength of the light will increase. When closely observed

Introduction Circular dichroism (CD) is form of light absorption spectroscopy that measures the difference in absorbance of right- and left-circularly polarized light (rather than the commonly used absorbance of isotropic light) by a substance. It is applicable for molecules have one or more chiral chromophores [1]. Circular dichroism = ΔA(λ) = A(λ)LCPL - A(λ)RCPL, where λ is the wavelength This technique measured a molecule over a range of wavelengths. All chiral molecules can be studied, particularly

Unit D Summary: Light and Geometric Optics 10.1:Light and The Electromagnetic Spectrum Chapter 10.1 covers light and the electromagnetic spectrum. This chapter starts off by describing how light is a form of energy that travels in waves. The properties of said waves include a crest (the highest point of the wave), the trough (the lowest point of the wave), and the rest position (the level of a wave without energy). The three most important properties of a wave are the wavelength, the amplitude

pigmentation of solution to indicate the presence of ions or sugars. The lambda max is the wavelength that gives the highest absorbance. This wavelength interacts most with the protein, during this time the solution absorbs the maximum amount of light. Electromagnetic

The known compounds ' results could be compared to the unknowns. The reason the light, of flame was emitted is because of electrons moving from excited state to ground state, releasing energy. Often times this energy is visible part of the electromagnetic spectrum, 400-750nm. Different wavelengths result in different colors. Knowing roughly what the the wavelength of the substances are, the energy of the substance can be found the equation E=ch/λ. The breakdown of this equation is E stands for energy

with the production, measurement and interpretation of spectra due to interaction of electromagnetic radiation with matter which is absorbed or emitted by atoms of a sample. This absorption or emission occurs when the atoms of the sample move from one energy level to another in presence of light. In other words, it is a science which deals how light interacts with matter. When atoms or molecules absorb electromagnetic energy, the incoming energy promotes the molecular system to a higher energy level

The emission spectrum of a chemical element is the spectrum of frequencies of electromagnetic radiation due to an atom or molecule making a transition from a high energy state to a low energy state. There are a lot of electron transitions for each atom. All transitions have a energy difference. After doing the atomic line emission lab my results came out in many different ways. During the lab, we went to five different stations. Throughout the stations, the light that we used to figure out the quantization

Spectroscopy is a term which refers to the interactions of various types of electromagnetic radiation with matter. It is also a study of the absorption and emission of light and other radiation by matter. Dependence of this process related to the wavelength of the radiation. Spectrometers are used to measure the properties of light over a specific portion of the electromagnetic spectrum. Fig 1: Dispertion of the visiable light 2. Theory Grating

One of the most useful and powerful plots in astrophysics is the Hertzsprung-Russell diagram. It originated in 1911 when the Danish astronomer, Ejnar Hertzsprung, plotted the absolute magnitude of stars against their colour (hence effective temperature). In 1913 the independent American astronomer Henry Norris Russell used spectral class against absolute magnitude. Their resultant plots showed that the relationship between temperature and luminosity of a star was not random but instead appeared to

The purpose of this experiment is to observe the characteristics colors produced by certain metal ions when vaporizing in a flame, and then identifying an unknown metal ions by using flame test. Electromagnetic radiation is energy that travels a wave, including microwave infrared radiation radio waves x-ray, radio waves,x-ray,gamma radiation, cosmic rays and visible light .there are two types of wavelength short wavelength such as x-ray, radiation and cosmic rays and long wavelength such as infrared
