A sound wave travels in air at a frequency of 500 Hz. If part of the wave travels from air into water, does its frequency change? Does its wavelength change? Note that the speed of sound in air is about 340 m/s, whereas the speed of osund in water is about 1500 m/s.

Frequency never changes unless the transmitter or receiver (or the medium) is moving. The speed of sound in air and water are different. Since wave speed is (frequency) x (wavelength), and frequency is constant, what does that tell you about what happens to the wavelength?
