In a Young's double slit experiment, if the wavelength of light is increased by 50 % and the distance between the slits is doubled then the percentage change in fringe width is

Options

  1. A75
  2. B50
  3. C25
  4. D15

Correct answer

A. 75

Step-by-step solution

Wavelength of light, ^ =50 Distance between the slit, d ^ =2 ~d fringe width, ^ = D ^ d^ aligned & = D 0.50 2 d =0.25 & | ^ - | 100 %=|0.25-1| 100 % & =75 % . aligned
