Question

a ray of light strikes a flat surface separating two glasses if the refractive index of the first glass is n = 1.92 and the second is n = 1.52 and the angle of the incident beam is 30 degrees. calculate the angle of refraction

a. 39.16 degrees

b. 30 degrees

c. 29.16 degrees

d. 35 degrees

Answer 1

given,

n1 = 1.92

n2 = 1.52

from snell's law

n1sin = n2sin

1.92sin30 = 1.52sin

0.96 = 1.52sin

sin = 0.96/1.52 = 0.6315

= angle of refraction = sin^-1(0.6315) = ...............Answer.

option a is correct.

hope this helps you.

please thumbs up.
