Snell's Law of Refraction
nβ sin ΞΈβ = nβ sin ΞΈβ
The ratio of sine of angle of incidence to sine of angle of refraction is a constant for a given pair of media
Incident & Emergent Rays
In a parallel-sided glass slab, emergent ray is parallel to incident ray but laterally displaced
Lateral Displacement
Perpendicular distance between incident and emergent ray paths, depends on angle and thickness
Real vs Apparent Depth
Objects appear raised in water due to refraction. Apparent depth = Real depth / n
Normal at Interface
All angles are measured from the normal (perpendicular) to the surface at point of incidence
