In Young's double slit experiment, an electron beam is used to produce interference fringes of width ₁ . Now the electron beam is replaced by a beam of protons with the same experimental set-up and same speed. The fringe width obtained is ₂ . The correct relation between ₁ and ₂ is

Options

  1. A₁= ₂
  2. BNo fringes are formed
  3. C₁ ₂
  4. D₁ ₂

Correct answer

D. ₁ ₂

Step-by-step solution

In Young's double slit experiment triangle = D d ₂ ₁ = ₂ ₁ ....(i) ₂ ₁ 1 ...(ii) From Eqs. (i) and (ii), we get ₂ ₁ 1 ₂ ₁
