Question

1. Get the timer out and let the wave be passing out the window to the right. Start the timer on peak zero passing out the window. Stop the timer when the 10th peak has reached the window.

Total time reading for 10 cycles= 20s.

Time for a single cycle= 2s.

What is the frequency you have measured? (find by taking the inverse of the time for a single cycle (this is a measurement based on the timer and may differ from the number you set)? f =____________________Hz 2.

For the conditions you set in problem 1, what is the wavelength of your wave (get the rulers out and make a measurement)?

λ (lambda)=_________________________cm

Answer 1

To find lambda you should provide wave graph or some additional information as distance between two consecutive peaks is lamda.

For your understanding I took V = 340 m/s and we know that V = frequency* lambda.
