In Young's double slit experiment, the intensity of light at a point on the screen where the path difference is is x units, . being the wavelength of light used. The intensity at a point where the path difference is 4 will be ( 2 =1, 2 =0 )

Step-by-step solution

When path difference = Phase difference aligned & = 2 =2 & & I=4 I₀ ^2 ( 2 ) & & x=4 I₀ ^2 ( 2 2 )=4 I₀ & & x=4 I₀ aligned When path difference = 4 Phase difference aligned & = 2 4 = 2 & I=4 I₀ ^2 ( 2 2 )=2 I₀ aligned Intensity, x^ = x 2
