Question

In Young's double slit experiment, if the width of
the slits are in the ratio 4:9 the ratio of the intensity
of maxima to the intensity at minima will be:
(1) 169 : 25
(2) 81: 16
(3) 25:1
(4) 9:4​

Answer 1

Answer:

Explanation:

9:4

Answer 2

Answer:

As per we know , in YDSE , spherical wavefront are formed so.

for spherical wavefront , I = E/AT

I is inversely proportional to the square ofab width of slits .

Explanation:

So, I Max/ I min= 81:16.( and)
