Light waves from two coherent sources arrive at two points on a screen with path difference of zero and ^ 2 . The ratio of intensities at the points is ( 0^ =1, =-1 )

Step-by-step solution

Given: Wave length = 2 Path difference of first wave x₁=0 Path difference of second wave x₂= 2 ₁= 2 x₁=0 Similarly, ₂= 2 x₂= Intensity of first wave I ₁=4 I ₀ ^2(0)=4 I ₀ Similarly, Intensity of second wave I₂=4 I₀ ^2 ( 2 )=0 aligned & I ₁ I ₂ = 4 I ₀ 0 = & : 1 aligned
