a sound wave of frequency 500 hz travels from air into water. the speed of sound in air is 330 m s-1 and in water 1490 m s-1. what is teh wavelength of the wave in a)air; b)water

The frequency stays the same, but, since
wave speed = (wavelength)*(frequency),

a) wavelength in air = V/f = 330/500
= 0.66 m

b) wavelength in water = 1490/500 = ?
