The maximum number of possible interference maxima for slit-separation equal to twice the wavelength in Young's double-slit experiment is

Options

  1. Ainfinite
  2. Bfive
  3. Cthree
  4. Dzero

Correct answer

B. five

Step-by-step solution

For interference maxima, d =n Here d=2 = n / 2 and is satisfied by 5 integral values of n (-2,-1,0,1,2) , as the maximum value of can only be 1 .
