Homework Statement
A dipper moving up and down makes waves in a ripple tank.
What will happen when the dipper frequency is increased?
(a) The waves will be closer together.
(b) The waves will move more quickly across the tank.
2. The attempt at a solution
From the equation, velocity of wave = frequency of wave multiply by the wavelength, I choose (b) since when frequency is increased, so will the velocity. However, the answer is (a). Why? Why is velocity held constant?
