Q1- A beam of monochromatic light is incident on a single slit of width 0.600 mm. A
diffraction pattern forms on a wall 1.30 m beyond the slit. The distance between the
positions of zero intensity on both sides of the central maximum is 2.00 mm.
Calculate the wavelength of the light.
Q2- Suppose light strikes a single slit of width a at an
angle B from the perpendicular direction as shown in
Figure 1. Show that the condition for destructive
interference, must be written as:
m = ±1,±2,±3, ... ..
sin@dark = m-
