Answer:
Angle of refraction
Explanation:
The incident ray is the ray before it reaches the surface.
The refracted ray is the ray after it reaches the surface.
n₁ is called the index of incidence.
n₂ is called the index of refraction.
θ₁ is called the angle of incidence.
θ₂ is called the angle of refraction.
They are related by Snell's law:
n₁ sin θ₁ = n₂ sin θ₂
