# NEET Physics Waves Questions Solved

Consider ten identical sources of sound all giving the same frequency but having phase angles which are random. If the average intensity of each source is I0, the average of resultant intensity I due to all these ten sources will be

(1) I = 100 I0

(2) I = 10 I0

(3) I = I0

(4) $I=\sqrt{10}\text{\hspace{0.17em}}{I}_{0}$
