A concave mirror that focuses light to a point.

A convex mirror that spreads out light rays.

$\frac{1}{f} = \frac{1}{u} + \frac{1}{v}$ describes mirror physics.

$M = -\frac{v}{u}$ calculates image size compared to the object.

Applications include headlights, solar concentrators, and shaving mirrors.

1. Incidence angle equals reflection angle. 2. Rays and normal in the same plane.

Images are virtual, upright, laterally inverted, and same size as the object.

When a mirror rotates by angle θ, reflected ray rotates by 2θ.

The angle between the incident ray and the normal. Deviation angle D = 2 × glancing angle.

Concave mirrors converge light, while convex mirrors diverge light.

The speed of light in a medium is given by v = c/n.

The angle of incidence for which total internal reflection occurs.

A measure of how much light slows down in a medium; calculated using angles.

The angle between the incident ray and the emergent ray after refraction.

Phenomenon where light is completely reflected at the boundary of two media.

Bending of light when it passes between different mediums.

Mathematical relation n = sin(i) / sin(r) describes the bending of light.

A form of energy that enables vision, traveling as electromagnetic waves.

Light exhibits properties of both particles (photons) and waves.

An area formed when an opaque object blocks light; contains umbra and penumbra.

A celestial event where one object moves into the shadow of another.

A simple device that uses a small hole to create an inverted image on a surface.
