Question

Q. Two slits in young's experiment have width in the ratio 1 :25 . what will be the ratio of intensity at the maxima and minima ??​

Answer 1

ⓖⓞⓛⓤ ⓜⓞⓛⓝⓘⓝⓖ ⓟⓖⓛ

I max / I min

= ( 1/5+ 1) ^2/(1/5-1) ^2

= 36 /16

= 9/ 4

Answer 2

Answer:

As, intensity I ∝ width of slit W Also, intensity I ∝ square of amplitude A

So the ratio of intensity at the maxima and minima is 1:9.
