A photon of wavelength 6000 Å is passed through a slit of width 0.2 mm

(a) Calculate the uncertainty introduced in the angle of emergence.

(b) The first minimum in the single slit diffraction pattern occurs at sin-1 (λ/b) where b is the width of the slit. Calculate this angle and compare with the angle obtained in part (a).

[Ans: radians]
