The intensity level of a sound of intensity of 10^(-12)wat t//cm^(2) is 40 dB. What is the zero level of intensity ?

An unpolarised beam of intensity I_(0) falls on a polariod. The intensity of the emergent light is :

The assignment problem is generally defined as a problem of …......

Two waves of same intensity produce interference. If intensity at maximum is 4I, then intensity at the minimum will be:
