Snell’s Law. Snell’s Law describes how a light ray behaves when it passes from a medium with index of refraction n. 1, to a medium with a different index of refraction, n 2. In general the light will enter the interface between the two medii at an angle. This angle is called the angle of incidence.

Optics Cheat Sheet. Reflection of Light. Reflection is the turning back of the light from the surface it hits. Incoming and reflected lights have same angle with the surface. If the surface reflects most of the light then we call such surfaces as mirrors.
equations is mathematically equivalent to the above quoted eld equations. 1.2.1 Vector elds Consider classical elds as simply functions of coordinates, T(x;y;z) for instance. You plug three numbers into T and get one number out - that would be called a scalar function or scalar eld.
The first textbook on mathematical methods focusing on techniques for optical science and engineering, this textbook is ideal for advanced undergraduates and graduate students in optical physics.
14 sie 2020 · Matrix methods. A light ray can be described by a vector (nα, y) with α the angle with the optical axis and y the distance to the optical axis. The new position of a light ray interacting with an optical system can be obtained using matrix multiplication: (n2α2 y2) = M(n1α1 y1) where Tr(M) = 1.
