Different wavelengths of light are refracted by different amounts when passing through a prism.

A rainbow is the result of sunlight being dispersed by numerous raindrops.

Light waves vibrating in a single plane.

Restricting the vibrations of a wave to a single plane.

A flat mirror that reflects light in a predictable manner.

The angle at which light strikes a surface equals the angle at which it bounces off.

Half the radius of curvature of a spherical mirror.

A curved mirror that reflects light outwards, creating a wider view.

A lens that causes parallel light rays to converge at a single focal point. It's thicker in the middle and thinner at the edges.

A lens that causes parallel light rays to spread out, making them seem to come from a single point called the virtual focus. It's thinner in the middle and thicker at the edges.

The distance between the center of a lens or mirror and its focal point.

An image formed by the actual convergence of light rays. It can be projected onto a screen.

An image formed by the apparent convergence of light rays. It cannot be projected onto a screen.

A distortion of an image caused by a lens or mirror that does not focus all light rays at the same point. This happens because the light rays don't converge or diverge at the same focal length.

A thin strand of glass that carries light with minimal absorption. Light travels through it by total internal reflection.

A phenomenon where light traveling through a denser medium reflects back into the same medium when it hits the boundary with a less dense medium at an angle greater than the critical angle.

When light waves hit a surface and bounce back without being absorbed. The incoming wave is called the incident wave, and the bouncing wave is called the reflected wave.

The angle at which light strikes a surface (angle of incidence) is equal to the angle at which it bounces off (angle of reflection).

When light waves pass from one transparent medium to another, they change speed and direction. This bending of light occurs because different materials have different densities, causing light to slow down or speed up.

A measure of how much light slows down when passing through a substance. Higher refractive index indicates a denser material and greater bending of light.

A mathematical equation that describes the relationship between the angle of incidence, angle of refraction, and the refractive indices of the two media.

The angle of incidence at which all light is reflected back into the original medium, resulting in total internal reflection.

The observed change in frequency of light waves due to the relative motion between the source of light and the observer. When a light source moves away from the observer, the light waves are stretched, and the frequency decreases, resulting in a shift towards the red end of the spectrum.
