A monochromatic ray of light enters into a glass slab (n=1.5) along the normal to the surface. The angle of deviation of the refracted ray is

Options

  1. A90^
  2. B45^
  3. C30^
  4. D0^

Correct answer

D. 0^

Step-by-step solution

When a ray of light enters a glass slab along the normal to the surface, it passes straight without deviation. So, angle of deviation is zero (0^ ) .
