Young's double-slit experiment is carried out by using green, red and blue light using one colour at a time. The fringe widths recorded are $β_{G}$ , $β_{R}$ and $β_{B}$ respectively. Then,

Options:

Answer:

Solution:

We know that fringe width is given by

$β = \frac{λD}{d}$

$∵$ $λ_{R} > λ_{G} > λ_{B}$

$∴ β_{R} > β_{G} > β_{B}$
