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

Options

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

Answer

a

Explanation

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.
