In a double slit experiment instead of taking slits of equal widths, one slit is made twice as wide as the other. Then, in the interference pattern

A

the intensities of both the maxima and the minima increases

B

the intensity of the maximum increase and minima has zero intensity

C

the intensity of the maxima decreases and that of minima increases

D

the intensity of the maxima decreases and the minima has zero intensity

Text Solution

Verified by Experts

The correct Answer is:
a

When slits of equal width are taken, then intensity at maxima is `4 a^(2)` and at minima it is zero `(I prop w)`.
When one slit is doubled, then intensity at maxima will increase whereas intensity at minima will no be equl to zero and will be finite.
