Vedclass · Answer

(A) For incoherent sources, the phase difference between the waves varies randomly with time. Therefore, the interference terms (cross-products) average out to zero over time.As a result, the resultant intensity is simply the algebraic sum of the individual intensities.Given $n$ sources each of intensity $I_0$, the resultant intensity $I_{net}$ is:$I_{net} = I_1 + I_2 + I_3 + ... + I_n$$I_{net} = I_0 + I_0 + I_0 + ... + n 	ext{ times}$$I_{net} = nI_0$

$n$ incoherent sources, each emitting beams of intensity $I_0$, are superimposed at a point. The resultant intensity at the point is:
