While tracing the path of a ray of light passing through a rectangular glass slab a student tabulated his observations as given below:

S.NO.

∠i

∠r

∠e

I

60°

40°

61°

II

50^o

36^o

51^o

III

40^o

28^o

39^o

IV

30^o

20^o

31^o

Solution

30^o

20^o

31^o

The correct option is D.

As per Snell’s law

fraction numerator sin space i over denominator sin space r end fraction equals n subscript 2 over n subscript 1

The ratio of the sine values of i and r should be 1.5.

Note: Refractive index of glass = 1.5 and refractive index of air is 1.
