Question 1 Report

The S.I unit for sound energy is

Answer Details
The SI unit for sound energy is J, which stands for Joule. Sound is a form of energy that is produced by the vibration of an object. When an object vibrates, it creates a disturbance in the air molecules around it, which causes the molecules to vibrate and carry the sound energy from the object to our ears. The amount of sound energy produced by an object is related to the amplitude (height) of the sound wave, which determines how loud the sound is, and the frequency (number of vibrations per second), which determines the pitch of the sound. The Joule is a unit of energy that is commonly used in physics to measure different forms of energy, including sound energy. When sound waves travel through a medium, they transfer energy to the medium, which can be measured in Joules. So, the SI unit for sound energy is J.
