Two wavelengths of sodium light 590 ~nm and 596 ~nm are used one after another to study diffraction due to single slit of aperture 2 10⁻⁶ ~m . The distance between the slit and the screen is 1.5 ~m . The separation between the positions of first maximum of the diffraction pattern obtained in the two cases is

Options

  1. A5.5mm
  2. B5.75mm
  3. C6.25mm
  4. D6.75mm

Correct answer

D. 6.75mm

Step-by-step solution

First maximum in single slit diffraction pattern is obtained at, x= 3 D 2 d array ll & x = 3 D 2 ~d = 3 1.5 2 2 10⁻⁶ (596-590) & x =6.75 ~mm array
