For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.
Suggest reasons for the differences in range of electromagnetic radiation detected by humans and other animals. Humans and other animals can detect different ranges of electromagnetic radiation due to their varying functions; this better suits them to their environment. Humans are able to see visible light (ROYGBV) only, as this allows them to distinguish between different objects and foods; ultraviolet and infrared vision is not necessary for their survival. Other animals have adaptive advantages to their environment, for example: • The Rattlesnake is able to detect infrared light via pits under their eyes. This allows them to easily detect their pray when hunting at night, giving them a better chance of finding food.
These changes could have been a result of the zone of polarizing activity (ZPA) (Page
However, as the universe has expanded, it has expanded faster than ever before. One theory that explains this is that a large dark energy force is pulling it apart. Dark Matter: Dark matter can’t release or reflect light; however, scientists can estimate the exact location of the dark matter using gravitational lensing.
Any good program needs a strong leadership team, and I have always wanted to be a strong leader because I love helping others be their very best. In our marching band program our section leaders are called FOG (For Others Greatness), they are chosen not only for their musicality but also for their ability to work with and guide others. The section leaders during my freshman year were incredible and I longed to be just like them when I was finally able to apply and audition for the position. I am on the color guard and do not play an instrument during the marching season, therefore my color guard skills would need to be at an elevated level in comparison to those of my peers. As the audition portion of the application came about I worked diligently

Red Bead Experiment Submitted By: Sarabjeet Singh (C0712487) Arshdeep Singh (C0719013) Harshpreet Singh (C0713155) Lovish (C0717943) Introduction Red and white beads experiment explained in video mainly based on the Integrated Environment, Safety and Health Management System, it includes all the all the core functions of ISMS environmental management aspects in all five core management functions that support work planning or work scope, hazard analysis, hazard control, work performance, and feedback and improvement. The instructor of the Red Bead experiment, Dr. Deming started with the definition of the work scope, the scope definition serves the purpose of stating exactly what it is that an organization does that is certified to be effectively controlled by the requirements of the standard. Dr. Deming gave different examples by the red and white beads.
Several colors other than green also play roles in this
A Doppler Ultrasound is used to measure the speed and direction of the blood cells as they move through a body’s vessel. Measures of speed and direction of blood cells are taken in these major arteries and veins in the abdomen, arms, legs, and neck. The movement of blood cells causes changes in pitch of the sound waves that are echoing back, which is referred to as the Doppler
Length contraction is the phenomenon in which a rapidly moving object appears to approach zero length as it accelerates. Though the object’s length appears unchanged in its own reference frame, an observer will see it contract at a rapidly increasing rate the closer it gets to the speed of light. The object’s length in an observer frame of reference is equal to its length at rest divided by the Lorentz factor. Due to this, an object’s length will asymptotically approach zero the closer its squared velocity gets to the speed of light. (Interestingly, this phenomenon provides further evidence that no massive object can travel at the speed of light.
This is similarly to the way sound was studied, except instead of a sound wavelength, it is a wavelength of a star's radiation. Astronomers use many properties of light to study everything from planets and their moons. This prompted the invention of the Hubble telescope, that proceeded to measure the Doppler shift, specifically finding the redshift of the galaxies. It was discovered that the farther away a galaxy is, the more quickly it fades.
This lab was quite difficult for me because I had absolutely no idea what I was doing or how I was even getting the answers, but I was able to complete it and I did learn a few things about this lab like how the Doppler Effect is used to discover an extrasolar planet. To begin with an extrasolar planet is any planetary body that is outside the solar system and that usually orbits a star other than the Sun. Direct evidence of extrasolar planets is very difficult to obtain. Astronomers use methods like the Doppler technique which are commonly used more when searching for extrasolar planets.
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.
The Doppler Effect says that there is an apparent change in received frequency due to relative motion between a sound source and sound
Wavelength of light is determined by amount of energy released when electron drops to lower orbit. Light is coherent; all the photons have same wave fronts that launch to unison. Laser light has tight beam and is strong and concentrated. To make these three properties occur takes something called “Stimulated Emission”, in which photon emission is
