Question

question 4—use the frequency slider and increase and decrease the frequency of the wave. observe the motion of the particles while the frequency increases and decreases. describe the difference between the motion of the particles when the frequency is increased and when it is decreased. question 5—wave speed—wave speed deals with the movement of the crests and troughs in the medium. basically, a higher wave speed will show the crests/troughs moving from left to right in a faster time than slower wave speeds. observe the differences in this by first setting the animation on a low frequency (0.1 hz), watch the wave speed, and then set the frequency on a high setting (1.0 hz) and observing the wave speed. does the change from the low frequency to a higher frequency cause any change in the wave speed? record your observations, and explain your answer.

Explanation:

For Question 4, when the frequency of a wave is increased, the particles in the medium vibrate more rapidly, moving back - and - forth more times per second. When frequency is decreased, the particle motion slows down. For Question 5, in a given medium, the wave speed is constant for a particular type of wave. Changing the frequency does not change the wave speed because wave speed is determined by the properties of the medium (such as its density and elasticity), not by the frequency of the wave.

Answer:

Question 4: When the frequency increases, the motion of the particles increases (they vibrate more rapidly). When the frequency decreases, the motion of the particles decreases (they vibrate more slowly).
Question 5: The wave speed does not change. The wave speed in a medium is determined by the properties of the medium and is independent of the frequency of the wave.
