Question

A sound wave passes through regions of the ocean with varying density. How do the varying wavelengths correspond to the density of the water? Select the two correct answers.(1 point)

Which of the following is the best answer?

a) Longer wavelengths correspond to lesser density of the water.

b) Longer wavelengths correspond to greater density of the water.

c) Shorter wavelengths correspond to greater density of the water.

d) Shorter wavelengths correspond to lesser density of the water.

Answer 1

Option (b) Longer wavelengths correspond to greater density of the water, and option (d) Shorter wavelengths correspond to lesser density of the water are correct. When a sound wave travels through regions of varying density, it experiences refraction, which causes the wave to bend. The bending of the wave is dependent on the speed of the wave, which is affected by the density of the water. In regions of higher density, the speed of the wave is slower, resulting in longer wavelengths. Conversely, in regions of lower density, the speed of the wave is faster, resulting in shorter wavelengths.
