Monochromatic light passes through two parallel narrow slits and forms an interference pattern on a screen. as the distance between the two slits is decreased, the distance between light bands in the pattern on the screen will
a. decrease.
b. increase.
c. remain the same.

b.increase.

Explanation:

The distance between the light bands and the distance between the two slits, are related as follows:

Here, y is the distance between light bands in the pattern, m is the number of light bands observed in the pattern, is the light's wavelenght, D is the distance between the two slits and the screen where the pattern is observed and d is the distance between the two slits. Thus, as the distance between the two slits is decreased, the distance between light bands will increase.
