You are standing on a dock, watching waves on a lake. Suppose the water waves have a speed of 1.2 m/s and are spaced 4.9 m apart. With what frequency do the waves meet the dock?
Homework Answers
Solution -
The speed of wave of 1.2 m/s
Wave spacing ( wavelength ) is 4.9 m
Frequency = speed / wavelength
= 1.2 / 4.9 = 0.249
Means 0.249 waves per second or 14.7 waves per minute.
Thanks

You are standing at position A and your friend at position B on a lake shore as shown in (Figure 1). Suppose that h = 3.0 m, l = 4.0 m. Someone throws a ball so that it lands on the lake surface at point S. The ball produces a circular pulse that propagates along the water surface with a speed of 0.30 m/s. Determine the ratio of the pulse amplitudes observed by you and your friend, assuming there is...
