Questions
The refractive index of a material of a prism of angles 450 – 450 – 900 is 1.5. The path of the ray of light incident normally on the hypotenuse side is shown in
detailed solution
Correct option is A
for the critical angle to be 450 1.414As glass has refractive index of 1.5, Its critical angle is less than 450 . Hence at both surfaces T.I.R. will be observed.Talk to our academic expert!
