Question

what is the relationship between angle of incidence and angle of refraction?

Answer 1

mew (refractive index)=sin i/sin r

i=angle of incidence
r=angle of refraction

Answer 2

According to Snell's law:
Refractive index of second medium with respect to first medium
Is equal to sine( angle of incidence )/sine( angle of refraction)
Mew= sin i / sin r.
Which is constant for two mediums


I hope, I made it clear
