The bending of sound wave when traveling forward changes direction as it passes through different densities.
- A.
Diffusion
- B.
Reflection
- C.
Refraction
- D.
Deflection
Correct Answer
C. RefractionExplanation
When a sound wave travels through different densities, such as from air to water or vice versa, its path is bent or changed in direction. This phenomenon is known as refraction. Refraction occurs because the speed of sound changes as it travels through different mediums, causing the wave to bend towards or away from the normal line. This change in direction is responsible for various auditory experiences, such as the bending of sound around obstacles or the focusing of sound waves in certain areas.Rate this question:
