A ray of light is incident at polarising angle such that its deviation is 24^ , then angle of incidence is

Options

  1. A24^
  2. B57^
  3. C66^
  4. D90^

Correct answer

B. 57^

Step-by-step solution

Here, i_ p =r+ i_ p =r+24 Moreover, i_ p +r=90^ ...(ii) From Eqs. (i) and (ii), we get aligned & i_ p + (i_ p -24 ) &=90^ & & i_ p &=57^ aligned
