A ray of light travelling through a rarer medium is incident at very small angle ' i ' on a glass slab and after refraction its velocity is reduced by 25 % . The angle of deviation is

Options

  1. A3 i 4
  2. Bi 4
  3. Ci 3
  4. D4 i 3 .

Correct answer

B. i 4

Step-by-step solution

aligned & n= i r = i r ( i is very small, i i) & n= c v = c 0.75 c = i r r & =0.75 i= 3 4 i & =i-r=i- 3 4 i= i 4 aligned
