Width of one of the two slits in a Young's double slit interference experiment is half of the other slit. The ratio of the maximum to the minimum intensity in the interference pattern is :

Options

  1. A(2 2 +1):(2 2 -1)
  2. B(3+2 2 ):(3-2 2 )
  3. C9: 1
  4. D3: 1

Correct answer

B. (3+2 2 ):(3-2 2 )

Step-by-step solution

I width I _ = ( I ₁ + I ₂ )^2 I ₁= I ₀, I ₂=2 I ₀ I _ = ( I ₁ - I ₂ )^2 I_ I_ = ( 2 +1)^2 ( 2 -1)^2 3+2 2 3-2 2
