Problem: A 0.52 mm-diameter hole is illuminated by light of wavelength 510 nm. What is the width of the central maximum on a screen 2.2 m behind the slit?

FREE Expert Solution

Location of dark fringes in a single slit is given by

sin θm=mλd

Where d is the slit width, m and m is the order.

The central maxima lies between two dark fringes with the order m = 1. 

For small angles measured in radians, sinθ ≃ tan θ ≃ θ
