Refractive index of crown glass is 1.51
Refractive index of air is 1.00
If light is passing through air to crown glass...
The angle of incidence is 30 degrees, what is the angle of refraction in the glass, in degrees?
I have no idea where I'm supposed to start with this, I could really do with some help <3

It's a basic Snell's law question... Snell's law connects refractive index and angle of refraction.

you'll need to learn Snell's law to do questions involving refraction angles and refractive indices.
