Problem 14-83 Diffraction
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) \(0.70^\circ\)]
Which is the correct diagram for part (a) of this problem?
