Problem 1DQ

When sound travels from air into water, does the frequency of the wave change? The speed? The wavelength? Explain your reasoning.

Step-by-Step Solution:

Solution 1DQ Step 1 of 3 : When atoms or molecules in the given medium are closely or tightly packed, sound waves can transmit with greater speed. In other words, sound travels faster in denser medium than in rarer medium.Hence speed of sound will be faster in case of water than air because water is more denser than air. Therefore, the sound speed changes when it travels for air to water. Step 2 of 3 : The energy of the light is related to the frequency; when the light enters the medium there are interference patterns that cause the apparent speed of light to change; if the frequency changed, the energy would not be conserved. The wavelength changes to balance the change in speed. Hence, when sound waves travels from air to water, frequency remain same.
