If the angle of incidence for a light ray in air is 45 degrees and the angle of refraction in glass be 30 degrees, find the refractive index of glass with respect to air. pls tell fast tomorrow exam

By Snell’s law,
Refractive index = sin(i)/sin(r)
= sin45/sin30
= 1.4
where ‘i' is the angle of incidence and ‘r’ is the angle of refraction.
Refractive index = sin(i)/sin(r)
= sin45/sin30
= 1.4
where ‘i' is the angle of incidence and ‘r’ is the angle of refraction.

refractive index
= sin i/ sin r
sin45/ sin 30
=√2 (1.41)
= sin i/ sin r
sin45/ sin 30
=√2 (1.41)
