sound waves quiz

Energy Wave

disturbances that transfer energy through space or a medium (like water, air, or fields) without permanently moving the matter itself

sound

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

Vibrations

an oscillation of the parts of a fluid or an elastic solid whose equilibrium has been disturbed, or of an electromagnetic wave.

Speaker

an apparatus that converts electrical impulses into sound, as part of audio equipment.

Electromagnetic Force

a fundamental interaction governing charged particles, attracting opposite charges (like protons and electrons) and repelling like charges, holding atoms together and creating phenomena from magnetism to light

Crest

.

the top of a mountain or hill.

Trough

its lowest point, the valley between two crests (high points), representing the maximum negative displacement from the resting position

Wavelength 

the distance between two identical points on a wave, like crest to crest or trough to trough

Amplitude 

the maximum displacement or distance a point on the wave moves from its equilibrium (resting) position, measured from the center line to the top of a crest or the bottom of a trough

Frequency

the number of wave cycles that pass a given point per second

Rest line

the undisturbed level of the medium when no wave is present

Pitch

its perceived highness or lowness, determined by its frequency

Echolocation

the location of objects by reflected sound, in particular that used by animals such as dolphins and bats.

Volume

quantity or power of sound; degree of loudness.

Compression Wave

a wave where particles of the medium vibrate parallel to the wave's direction, creating alternating areas of high density/pressure (compressions) and low density/pressure (rarefactions) that push energy forward

Wave speed

Wave speed is how fast a wave travels through a medium, measured as distance per time

Medium

the substance (solid, liquid, gas, or even vacuum) through which a wave travels, transferring energy without permanently displacing its particles

Thunder

a resounding loud deep noise.
