Problem
A sound produced in air enters water without any change in its frequency. Compared with its wavelength in air, its wavelength in water will
(a) λ will remain the same because the frequency f is unchanged.
(b) λ will increase because the speed of sound v is greater in water.
(c) λ will decrease because the speed of sound v is greater in water.
(d) λ cannot be predicted without knowing the temperature of water.
