A transverse wave can be demonstrated using a rope. Describe how the hand must move to make a transverse wave of frequency 5 Hz.
For a transverse wave to move from left to right, the hand must move in a to and fro motion vertically.
There should be 5 oscillations of the hand in 1 second.
A wave travels in a medium with a certain speed. What must be done to double the wavelength of the wave in the same medium?
Since the wave is in the same medium, the speed does not change.
From speed of wave = frequency x wavelength, the source of the wave should be at half the frequency in order to achieve a doubled wavelength.
Describe what happens to water waves as it travel from a deep to shallow region.
When water wave travels from a deep to shallow region, its speed is slowed down while its frequency remains constant.
Since speed of wave = frequency x wavelength, the wavelength will decrease too.
