20.01
“The particles in the pulse travel from one place to another”, it’s incorrect because the definition of wave is transferring energy without transferring any mass. So particles don’t travel in pulse.
20.03
“The wave continues to travel for 0.20s before stopping”. Its wrong since period is the time for one complete vibration and it doesn’t relate to the time that wave stops.
“The wavelength is 0.20s”. It’s wrong, because 0.20s is the wave’s period not its wavelength. Wavelength is length of one complete vibration and its unit is (m).
20.04
“The wave disturbance travels 300m for each wavelength”. Not correct, because wave speed is the speed of wavelength over its period and it doesn’t relate to wave disturbance.

Because, wave is transfer of energy not a particle. Wave speed is the speed of one particular distance in wave.
24.05
“The period of the wave is 4.0m”, is wrong. Wavelength is the length of one period and its different with period. The unit of period is (s).
“The wave continues to travel for 4.0m before stopping”, is wrong. The wavelength doesn’t relate to the point that wave will
The wavenumber was changed to that for the second overtone and the previous two steps were completed for that wave range.
Light is a form of energy that behaves in some ways like waves. Light waves have a range of wavelengths. A wavelength is the distance between any point on one wave and the corresponding point on the next wave. Different wavelengths of light appear to us as different colors. Light that contains all wavelengths in the same proportions as sunlight appears white. See LIGHT.
In longitudinal waves the object doesn’t exactly follow the waves fully instead the object moves in a back and forth motion while the waves continues to move forward through the object. While in transverse waves the object doesn’t follow the waves as well and just moves up and down in the same position.
In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.
But per the question, we need to use (2 x 10^8 m/s) for the propagation delay.
“The particles in the pulse travel from one place to another.” This sentence is wrong about the propagation of a pulse because particles do not travel in a pulse. They just stay in one place moving up and down and interact with each other. Because the particles are moving, energy are transferred through the medium from one place to another.
At what point does the Wave get out of control? Support your choice with specific events.
Give 2 reasons why circular water waves decrease in amplitude as they travel away from the source?
Eventually Laurie persuades her boyfriend (Wave member) that ‘The Wave’ is out of control and he agrees after nearly injuring her is a disagreement about the experiment. The two then take to Mr Ross to stop the social assesment, he
The waves were beginning to be pulled back similar to that of a metal being attracted to the magnet. It was not stopping, the waves were continuously being pulled
Also, when looking at the filtrate values under the short-wavelength, a value of 0.44 appears to hint at the existence of the cis,trans-isomer which has a literature value of 0.41. The three values for the filtrate under the long-wavelength make sense as well, being that the value of 0.28 belongs to the oxide, the 0.36 to the trans,trans, and the 0.44 to the cis,trans.
The objective in Lab 8 is to measure wavelength of five emission lines of light and a laser beam through the principle of light interference.

The red bar on the left acts as the driving piston. If it moves in a sinusoidal manner from left to right, then the wave that is produced will be a sinusoidal wave. Since the wave is sinusoidal, the wavelength, amplitude and frequency are constant. This is seen in nature as a tuning fork, which produces a periodic sound wave. In a one dimensional tube as shown above, each particle undergoes simple harmonic motion. The volume that is contained in one wavelength also undergoes this same motion. We can represent the displacement of this volume as:
Wavelength: Microwave is a short wavelength wave. The wavelength of the microwave transmitted by Bluetooth is about 12.5cm. (Miller, A.B. 2001)
