What is the intensity of a sound wave?
A.the perception of a person about the frequency of a sound wave
B.the energy a sound wave carries per second through a unit area
C.the number of waves that pass by a point per unit time
D.the distance in metric units that a sound wave moves per unit time

Answers

Answer 1

The intensity of a sound wave is defined as the energy the sound wave carries per second through a unit area. It is typically measured in watts per square meter (W/m²) and is related to the amplitude (or height) of the sound wave. The intensity of a sound wave determines its loudness, with higher intensity corresponding to louder sounds. Option B is the answer.

What is sound wave?

A sound wave is a type of wave that is created by the vibration of an object, such as a speaker or a musical instrument. When an object vibrates, it creates a disturbance in the surrounding medium, such as air, which causes the air particles to move back and forth in a pattern.

As the vibrating object moves back and forth, it creates a series of compressions and rarefactions in the air, which propagate outward in all directions as a longitudinal wave. These compressions and rarefactions travel through the air at a speed that is determined by the properties of the medium, such as its density and elasticity.
