It is indicated by symbol I and is the power transmitted per unit area by sound waves
It depends on the density of the medium, v is the velocity of the wave, omega is the angular frequency of the wave and sm is the amplitude of vibrations.
We can use logarithmic scale to describe intensity of sound as well so that instead of describing intensity I as large numbers going into trillions, we can make it a lot more convenient by handling smaller numbers. And these numbers are called sound levels or decibels
Who can use:
Class 11 and 12 students (CBSE, ICSE, NCERT)
IIT-JEE Preparation (JEE Main and JEE advanced)
K-12
Advanced Placement (AP Physics)
Subject SAT
