Consider a glass slab which is silvered at one side and the other side is transparent. Given the refractive index of the glass slab to be 1.5. If a ray of light is incident at an angle of 45^ on the transparent side, then the deviation of the ray of light from its initial path, when it comes out of the slab is

Options

  1. A180^
  2. B120^
  3. C45^
  4. D90^

Correct answer

D. 90^

Step-by-step solution

The ray diagram for the given situation is shown below Hence, emergent rays comes out at angle of 90^ from incident ray.
