A ray of light traveling from a rectangular glass block of refractive index 1.5 into air strikes the block at an angle of incidence of 30. Calculate its angle of refraction.

MYSCHOOL the answer should be 48.6 not 19.47. As a quick way of checking, the angle of refraction should be greater than angle of incidence since the light is travelling from a denser medium to a less dense medium(it should bend further away from the normal)
MYSCHOOL please make corrections.
