A 440 Hz sound wave in 20°C air propagates into the water of a swimming pool. What are the wave’s (a) frequency and (b) wavelength in the water?
Added by Matthew G.
Step 1
The frequency of a sound wave does not change when it moves from one medium to another. Therefore, the frequency of the sound wave in water is the same as in air, which is 440 Hz. Show more…

A 420 Hz sound wave in 20∘C air propagates into the water of a swimming pool. Assume that the wave's speed in the water is 1480 m/s. Part A What is the wave's frequency in the water? Part B What is the wave's wavelength in the water?

A $256 \mathrm{Hz}$ sound wave in $20^{\circ} \mathrm{C}$ air propagates into the water of a swimming pool. What are the water-to-air ratios of the wave's frequency, wave speed, and wave length?
If the velocity of a 440 Hz sound is 1,125 ft/s in the air and 5,020 ft/s in seawater, find the wavelength of this sound (a) in air, (b) in seawater.
