WebJan 1, 2016 · Any ray traveling in parallel to the principal axis (red traces) is refracted, i.e. bent, to reach the focal point at the other side of the lens. Rays traveling through the focal … WebThe law of refraction, or Snell's law, relates the angles of incidence and refraction and the indices of refraction according to the equation: \(n_1\sin\theta_1=n_2\sin\theta_2.\) When light travels from a medium with a low refractive index to one with a high refractive index, the refracted beam bends toward the normal.

WebMar 4, 2024 · In the geometric optics limit any general optical system can be associated with a ray which can be traced through two basic types of traversal of the ray: translation and refraction. The law of refraction is therefore the central tool for ray-tracing. A ray can be described in an optical system by its coordinates. We will soon define the ray ...
