Explanation:
Whenever the light passes through hole or slit then it tends to bend that is actually a diffraction. It will then made the interference pattern of light and dark bands that due to constructive and destructive interference.
So by using the equation of diffraction,
dsinA = nL
SinA is a geometric component it can be written as,
∵ x is the distance from screen.
∵ y is the half of the width of central maximum.
now by putting the values in mm,
d = 2.15× mm
