Aray of light is incident on a flat surface of a block of polystyrene, with an index of refraction of 1.49, that is submerged in water. the ray is split at the surface, where the angle of refraction of the transmitted ray is 18.6°. what is the angle of reflection (in degrees) of the reflected ray?
Answers: 1
= Index of refraction of each material
Angle of incidence or Angle of Reflection
Angle of refraction 
Index of refraction of water
