A sound wave of frequency 1700 Hz travels through the air and then passes into water. The speed of sound in air is 340 m/s. The speed of sound in water is 1500 m/s.
State what happens to the frequency of the sound wave as it passes from the air into the water.
Calculate the wavelength of the sound wave in the water.
Explain why the wavelength of the sound wave changes when it passes from the air into the water.
