Question

What happens if we use white light instead of monochromatic light in interference phenomenon​

Answer 1

Answer:

When we use white light in place of monochromatic light then only central fringe looks white and other fringes of different colour are observed. It is becaused central fringe for all the colours are formed at central point so it becomes white after mixiing up.

Answer 2

explain-

In an interference experiment monochromatic light is replaced by white light, we will see: Answer: ... Each light will have its dark and bright fringes independently, but each bright fringe light will coincide at y= 0, i.e. for a center.
