Question

n identical coherent isotropic sources each having power P are kept symmetrically on the periphery of circle $$x2+y2=R2$$ .  The resultant intensity detected by a detector placed at $$0$$,$$0$$,R is $$I1$$ and the resultant intensity at $$0$$,$$0$$,$$2R$$ is $$I2$$ . The ratio of  $$I1$$  and  $$I2$$ is

Infinity Learn · Accepted Answer

Path difference at the both the points is zero, but since $$2nd$$ point is farther than $$1st$$ point, Hence , $$I2$$ < $$I1$$
