I can't seem to get the 48.2 to be honest o.0
I'll let someone help u.
Arthur Bon Zavi:
n = sinr/sini OR n = sini/sinr in any form
sinr/sin30 = 1.49 OR sinr = 1.49 × sin30
48.1°
^ This is from the mark scheme.
The answer should be that found by you, because when it escapes from the prism, it will have a greater speed and therefore the refractive index will be low.

Can you tell me why are they multiplying, when the formula is n = sin i/ sin r :-|
