Problem 14-83 Diffraction - Part 2 - A

A point source emits light of wavelength \(520\; nm\) toward a single slit of width \(0.085\; mm\). The light creates a diffraction pattern on a screen located \(2.2 \;m\) from the screen.

(a) What is the width of the central maximum?
(b) What angle do the first order fringes subtend with the slit?

[Ans. (a) \(2.7 \;cm\)   (b) \(0.70^\circ\)]

Accumulated Solution

Diagram B of the width of the central maximum.

No. That is for the minima in double slit interference.
