Question

If a monochromatic source of light is replaced by white light, what change would you observe in the diffraction pattern?

Solution

Following changes will be observed

(i) Central fringe will be bright but subsequent bright fringes will be coloured instead of just being bright.

(ii) Fringe width, angular fringe width will not be constant.
