Question

Which of the following changes when sound is reflected

Answer 1

Explanation:

When sound travels in a given medium, it strikes the surface of another medium and bounces back in some other direction. This phenomenon is called the reflection of sound. During reflection, the frequency, speed and wavelength of the wave do not change.

Answer 2

When sound is reflected, the amplitude changes.

• The amplitude of a sound wave is proportional to contrast in pressure. If the amplitude escalates, the sound is regarded as booming, and if the amplitude drops, the sound is seen as faint.
• The amplitude of a location where particles are vibrating from their equilibrium position when there is a maximum displacement movement is measured.

• When the energy of a sound wave is lost as the amplitude of that sound wave gradually decreases, the state is said to be in the damping condition of that wave.
• The distance between the wave's mean location and the trough or crest is also known as the amplitude of the wave.
• A sound wave's amplitude is proportional to the loudness of that sound wave.
