Question

Consider a ray light passing through a rectangular glass slab. Let the emergent ray shift laterally by a distance $x$.The shift $x$ depends on

• A. angle of incidence
• B. refractive index of the material of the slab
• C. width of the slab
• D. all the above

Answer 1

Answer: (D)

all the above

Lateral shift$=t\frac{\sin (i-r)}{\cos \left(r\right)}$

t=Thickness of the slab

i=incident angle

r=refraction angle
