In Young's double slit experiment, fringe order is represented by

m

, then fringe width is

Options

AIndependent of $m$ .
BDirectly proportional to $m$ .
CDirectly proportional to $(2 m+1)$ .
DInversely proportional to $(2 m+1)$

Correct answer

A. Independent of $m$ .

Step-by-step solution

The fringe width is given by

\beta=\frac{\lambda D}{d}

Here

D

is the separation between screen and slits and

d

is the separation between slits.
