What is the lateral shift of a ray refracted through a parallel-sided glass slab of thickness ' h ' in terms of the angle of incidence ' i ' and angle of refraction ' r ', if the glass slab is placed in air medium?

Options

  1. Ah (i-r) r
  2. Bh (i-r) r
  3. Ch
  4. Dh (i-r) r

Correct answer

B. h (i-r) r

Step-by-step solution

aligned & A B=h r & B C=h r ( i -r) & B C= h (i-r) r aligned
