HELP!!! Couldn’t solve this problem?
Light enters a plate of borosilicate crown glass at an angle of 51.7 ◦ with respect to the normal to the air-glass surface. If the index of refraction of the glass is 1.52, find the angle made by the refracted beam with the normal. (Answer in units of ◦.)
Using Snell’s Law we get na*sin(thetaa) = nb*sin(thetab)
So thetab = arcsin(na*sin(thetaa)/nb) = arcsin(1*sin(51.7)/1.52) = 31.1o
