A light ray of wavelength 610 nm is incident
at an angle θ on the top surface of a block of
polystyrene surrounded by water.
Find the maximum value of θ for which the
refracted ray will undergo total internal re-
flection at the left vertical face of the block.
(Assume the refractive index of water is 1.333,
and the refractive index of polystyrene is
1.487.)
Answer in units of



I looked for the critical angle and then, since its a right angle just get the angle measure that would equal the incident angle at the top
