Question

Light travelling in air strikes a glass plate at an angle π1 ,

where π1 is measured between the incoming ray and the glass

surface. Upon striking the glass, part of the beam is reflected

and part is refracted. If the refracted and reflected beams make

an angle of 90°with each other, what is the refractive index

of the glass? What is the critical angle, Numerical aperture

and acceptance angle for the glass?. Assume your own π1.

Suggest your opinion to achieve total internal reflection.​
