Sound waves

Wavelength

the distance from one wave to another

Crest

top of a wave

amplitude

the max distance from one wave to another from the resting line

trough

the bottom of a wave

energy wave

a disturbance transferring energy

sound

vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.

vibration

a rapid motion of the particles of an elastic body or substance back and forth

electromagnetic force

a fundamental interaction governing charged particles, attracting opposite charges

frequency

the number of wave cycles, or oscillations, that pass a fixed point in a given amount of time, typically one second

rest line

the line that starts a wave

pitch

highness or lowness, determined by its frequency

echolocation

a biological process where an animal emits a sound and listens to the echoes that bounce off objects to navigate and find prey

compression wave

a type of longitudinal wave where the particles in the medium are pushed together, creating areas of high pressure

wave speed

the rate at which a wave's disturbance travels through a medium, measured as distance per time

medium

the intervening substance through which impressions are conveyed to the senses or a force acts on objects at a distance.

thunder

a loud rumbling or crashing noise heard after a lightning flash due to the expansion of rapidly heated air.
