A student uses a ripple tank to investigate the behavior of water waves as they travel from a deep water region into a shallow water region.
State the formula that relates wave speed, frequency, and wavelength.
As the waves transition from the deep region to the shallow region, their speed decreases. State which property of the wave (frequency or wavelength) remains constant, and explain why the other property must change.
Waves in the deep region of the ripple tank travel at a speed of 15.0 cm/s with a wavelength of 6.0 cm. In the shallow region of the tank, the wave speed decreases to 9.0 cm/s. Calculate the wavelength of the waves in this shallow region.
