Analysis Of Amplitude And Longitudinal Waves Using Slinky Spring

641 Words3 Pages

Introduction The purpose of this lab was for students to understand and explore their knowledge of standing, transverse, and longitudinal waves using a Slinky spring. It also served to investigate and verify the connection between waves and their specific properties such as: amplitude, wavelength, frequency, and period. Amplitude is directly related to the amount of energy transmitted by a wave. For a transverse wave, the amplitude is the maximum displacement above or below its position of equilibrium. the amplitude of a longitudinal wave is the maximum increase or decrease in pressure in the medium as the weave travels through. Another key term to know is wavelength, which is the distance from one point on a wave to the same point on the next …show more content…

The group’s hypothesis was that as the slinky moved faster and faster the frequency and wavelength will also directly continue to get larger.

Materials and Methods The materials used in this lab report are as follows: meter stick, nylon string, 10cm, Slinky, and stopwatch. The group did three separate experiments for each type of wave. For the transverse wave experiment the group picked a coil of the slinky about half away from each end and tied the nylon string tightly in a single knot. Then they placed the slinky on the floor. After they measured three meters with a meter stick and two people were on each end holding the slinky. Then with a rapid motion, one person shook one end of the slinky sideways and back to its original position to create a single pulse with an amplitude of about 20cm. Then they observed the transverse wave as it traveled the length of the slinky, noting the motion of

The three most important properties of a wave are the wavelength, the amplitude, and the frequency. The wavelength is the distance from one point on a wave to the next identical point on the next wave. The amplitude is the distance from a waves rest position to either the crest or trough of the wave. The frequency is a rate which represents the amount of times a wave repeats

The experiment used a light of a single color, or monochromatic light, and two closely spaced slits or pinholes. He realized that the bright fringes of light resulted from light waves from both holes arriving crest to crest, creating a constructive interference. He also realized that the dark areas resulted from light waves coming from trough to crest, creating a destructive interference. The interference fringes made were straight lines. This interference experiment demonstrated the wave nature of light idea generated by Huygens 200 years earlier.

Wave properties: Frequency: How many waves go past a point in one second; measured in hertz (Hz). The higher the frequency, the more energy in the wave. 1 Ask the children to play 'verbal tennis' in partners on words that describe sounds (eg loud, quiet, vibration, pitch). One child says one word related to sound, then their partner says another and so on. 2 Ask the children what things make sounds.

In "Passage 1: Sound is All around Us, Sound is Energy" Jason Torres claims that sound is a form of waves that vibrate in one directions called longitudinal waves. "The distance between two adjacent compressions, two adjacent rabout the longitudinal arefactions, or a single compression and rarefaction combined is a wavelength of a sound wave. " This is Jason Torres ' definition of Longitudinal Waves. The wave measures the sound and pitch. This pitch and sound can differ due to the extent of energy/waves released.

There are two main types of waves. The first is called a transverse wave. Transverse waves occur when a disturbance creates oscillations perpendicular to the direction of the travel of the wave. The second is called a longitudinal wave. Longitudinal waves occur when the disturbances are parallel to the direction of propagation.

“[W]hen you have walls very close to one another the frequencies go back and forth… [At the time of discovery,] they described it as the sound of angels’ wings,” said James Donahue, one of the experts involved in the project. After Donahue heard this phenomenon for himself, he commented, “I heard the standard sweep tone until it hit 6 kilohertz… I could hear the fluttering. I said, ‘Wow, those are the angels.’” Showing Donahue’s emotion towards this sound strongly appeals to pathos and allows the audience to relate to what the angel wings represent, such as hope, enlightenment or

Max Moore Mrs.Carey Language Arts Per.2 10 April 2024 Rogue Waves And Tsunamis Two big waves, rogue waves and tsunamis, both are very dangerous, and both carry water with lots of force. Tsunamis and rogue waves both do damage in the same way, they can destroy oil rigs, and ships. They may seem the same at first, but they are actually very different. Rogue waves are found deep in the ocean and are made from wind. First, rogue waves are found far out at sea, then they stay in the middle of the ocean.

Rogue Waves Description Rogue waves are surface waves over water that are unpredictable and have unnaturally large amplitude. To be classified a rogue wave, a wave must be more than twice the significant wave height, or the average of the largest third of waves in a given period of time. These waves are dangerous, even to large ships, and can even flow ashore, pulling people into the water. Research on the topic is still ongoing so there are many different proposed mechanisms for the creation of rogue waves.

In “My life with the Wave” poem that is written by Octavio Paz, he speaks about the phases a couple goes through when in love and how jealousy eventually ended the relationship, a passion that turned cold. The surrealist prose poem is a story stating the elements of love and hatred running through the relationship amid the narrator and the wave, which are both, physical and emotional. The wave is conferred with human qualities and the wave signifies a woman. This paper will focus on jealousy and how it is normal and healthy in a relationship unless it goes too far, that’s when it becomes unhealthy.

Sound assignment All sounds are created by vibration. The vibrations create a sound wave in the air by pushing air particles together and spreading them apart many times. 1) Explain what frequency and pitch mean when referring to sound Frequency= The rate per second of a vibration constituting a wave, either in a material (sound waves), or in an electromagnetic field (radio waves and light) pitch= the quality of a sound governed by the rate of vibrations producing it, the degree of highness or lowness of a tone. -google definition 2) Why does sound travel through different materials at different speed?

Another concept that was used in this artifact was Amplitude. The amplitude is how high or low on the graph. In other words the amplitude is known as half the distance between the maximum and minimum values of the function. To find the amplitude you can use the formula of A= D/F. In this formula the D represent the distance traveled by the wave and the F represents the frequency of the wave.

The mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.

The tuning fork’s vibrations were directing along the length of the tube with its prongs lined up along it. The tube’s length was adjusted until the volume of the sound was at its highest amplitude. Then the length of the column was measured by its resonance. These steps were repeated for the other two tuning forks. The hypothesis was not supported because the highest frequency had the lowest length of the tube.

The novel “The Sound of Waves” by Yukio Mishima is a portrayal of a love story. In the story Yukio Mishima brings attention to the Westernization of Japan. He believes that the new time is corrupted. Everyone associated with the modernization spreading is corrupted and those who aren’t associated with the westernization of Japan are more pure and aren’t corrupted. Mishima uses many literary elements throughout the book to convey this broader theme, three of them being characterization, foreshadowing, and imagery.
