Question

5. If the angle of incidence for a ray of light moving
from air to glass is 45° and the angle of refraction in
glass is 30°, find the refractive index of glass. ​

Answer 1

Answer: Hi friend,

Here is your answer,

refractive index = sin i / sin r

                         = sin45/sin30

                         = (1/root2)/(1/2)

                         = 2/(root2)

                          = root 2
