Sound wave of wavelength 0.5 m in air passes in to water. What is its wavelength in water? Also find the frequencies of the wave in air and water (Velocity of sound in air and water are 350 m/s and 1400 m/s respectively)

Correct Answer: 0

Solution

PLACEHOLDER ANSWER - the question has two answers. The frequency does not change when sound passes into another medium, and in air it is $$\frac{350}{0.5} = 700\text{ Hz}$$, so it is 700 Hz in both. The wavelength in water is $$\frac{1400}{700} = 2\text{ m}$$.
