Wave Velocity

Question 1

Wave velocity formula

Answer 1

Wave velocity (m/s) = frequency (Hz) x wavelength (m)

Question 2

As frequency increases wavelength decreases. Suggest why

Answer 2

The higher the frequency, the more the waves meaning that they get closer together, making the distance between them smallr

Question 3

As frequency decreases

Answer 3

Wavelength increases

Question 4

Explain how finding the velocity of sound is different from finding the velocity of ripples.

Answer 4

You find the velocity of ripples using frequency and wavelength, and the velocity of
sound using distance and time.

Question 5

Write down and explain whether moving your hand faster when you make a transverse wave on a slinky spring will increase the velocity of the wave on the slinky.

Answer 5

No, speed is the distance travelled per second, and frequency is the number of waves
per second.
Therefore changing the speed of your hand affects the frequency, not the speed.
