Overview

Refraction at curved surfaces explains how light changes direction when it passes through curved interfaces such as a vessel wall or a lens. The main ideas are centre of curvature, pole, principal axis, focal point, and the rules for ray behaviour through curved surfaces and thin lenses.

Key Concepts

The centre of curvature is

The centre of curvature is the centre of the sphere of which the curved surface is a part. The pole is the centre of the curved surface. The principal

A ray bends towards the normal

A ray bends towards the normal when it goes from a rarer medium to a denser medium and away from the normal when it goes from a denser medium to a rar

The focal point is the point

The focal point is the point where refracted rays parallel to the principal axis meet, or from which they appear to diverge. The focal plane is the pl

For refraction at a spherical surface

For refraction at a spherical surface, the relation is n₂/v - n₁/u = (n₂ - n₁)/R. For a plane surface, R approaches infinity, so the special case beco

Distances measured along the direction

Distances measured along the direction of incident light are positive and distances measured opposite to it are negative. Heights above the principal
