A Young's double slit experiment is performed with white light.

Options

A. The maximum next to the central will be red.
B. The central maxima will be white
C. The maxima next to the central will be violet
D. there will not be a completely dark fringe.

Answer

B, C, D

Explanation

if it is performed with white light the central point will have maxima of the colours, hence it will look white.
`beta=(lamdaD)/(d)`: as `lamda_(v)` is minimum
So first maxima after white as will be that of violet. So there will be no dark fringe as it is not possible be have minimas of all the colors at the same point.
