(Hindi) Intensity of sound wave
Lesson 7 of 21 • 2 upvotes • 8:59mins
Rajesh Kumar
Intensity of sound wave defined by average power crossing per unit area. Watt/meter2.intensity directly related to average energy passing through space from one point to other point. I proportional to square of pressure amplitude (p०).A sound wave's amplitude relates to changes in pressure. The sound is perceived as louder if the amplitude increases, and softer if the amplitudedecreases. ... The average amount of energy passing through a unit area per unit of time in a specified direction is called the intensity of the wave.
