The part of a longitudinal wave where the particles of the medium are close together.

Highest point of a wave

the number of complete wavelengths that pass a point in a given time

electromagnetic radiation with wavelengths longer than visible light but shorter than radio waves

A light wave is a type of electromagnetic wave. Light waves on the electromagnetic spectrum include those that are visible as well as those that are invisible to the human eye.

a wave in which the particles move parallel to the path of the wave

waves that require a medium through which to travel

Material through which a wave travels

a part in a longitudinal wave where the particles are spread apart

The bouncing back of a wave when it hits a surface through which it cannot pass.

a tone's experienced highness or lowness; depends on frequency

The bending of a wave as it passes at an angle from one medium to another

a process by which light is redirected as it passes through a medium

A disturbance that travels through a medium as a longitudinal wave

Waves that move the medium at right angles to the direction in which the waves travel

Lowest point of a wave

Abbreviated UV light and also known as cold light or actinic light; invisible light that has a short wavelength (giving it higher energy), is less penetrating than visible light, causes chemical reactions to happen more quickly than visible light, produces less heat than visible light, and kills germs.

Horizontal distance between the crests or between the troughs of two adjacent waves

a back and forth movement of matter

Electromagnetic radiation that can be seen with the unaided eye

A disturbance that transfers energy from place to place
