If two incoherent sources each of intensity I0 produce wave which overlaps at some common point, then resultant intensity obtained is

Question

If two incoherent sources each of intensity I0 produce wave which overlaps at some common point, then resultant intensity obtained is (A) 4 I0 (B) 2 I0 (C) (I0/2) (D) dependent on phase difference

Tardigrade Admin · Accepted Answer

When the sources are incoherent there is no interference and resultant intensity is I1+I2. For sources of same intensity I0, resultant intensity will be 2 I0.

Q. If two incoherent sources each of intensity $I_{0}$ produce wave which overlaps at some common point, then resultant intensity obtained is

$4 I_{0}$

$2 I_{0}$

$\frac{I _{0}}{2}$

dependent on phase difference

When the sources are incoherent there is no interference and resultant intensity is $I_{1} + I_{2}$ . For sources of same intensity $I_{0}$ , resultant intensity will be $2 I_{0}$ .

Q. If two incoherent sources each of intensity I0​ produce wave which overlaps at some common point, then resultant intensity obtained is
