In Young's double slit experiment, the intensity at a point where the path difference is 6 ( 1 being the wavelength of the light used) is I . If I₀ denotes the maximum intensity. I I ₀ , is equal to

Options

  1. A1 2
  2. B3 2
  3. C1 2
  4. D3 4

Correct answer

D. 3 4

Step-by-step solution

In YDSE, x= 6 , I ₁= I ₂ Phase difference, = 2 x= 2 6 = 3 aligned & I = I ₁+ I ₂+2 I ₁ I ₂ & = I ₁+ I ₁+2 I ₁ 3 =3 I ₁ & I ₀= ( I ₁ + I ₂ )^2= (2 I ₁ )^2=4 I ₁ & I I ₀ = 3 I ₁ 4 I ₁ = 3 4 aligned
