Waves

Wave

A disturbance that carries energy. Ex: Sound Waves

Medium

Something a wave travels through. Ex: Gas, Liquid, Solid

Energy

Ability to create change. Ex: Batteries

Amplitude

Distance between the crest and equilibrium. Ex: Loudness

Frequency

The amount of times a wave passes through per second. Ex: 5 Meters Per Second

Wavelength

Distance between to crests, troughs, rarefactions, or compressions. Ex: 5 Meters

Destructive Interference

When 2 waves overlap and the resulting amplitude is less smaller. Ex: Noise cancelling headphones

ROYGBIV

Colors part of visible light spectrum. (White Light). Ex: Red

Constructive Interference

When 2 waves overlap and the amplitude is larger. Ex: 2 speakers

Equilibrium

The resting point. Ex: A flat wave

Electromagnetic Wave

A transverse wave consisting of electrical and magnetic fields that carry energy. Ex: Radio waves

Sound Wave

A longitudinal wave that carries energy. Ex: Music from a guitar

Longitudinal Wave

A wave that moves parallel to the medium. Ex: Sound wave

Transverse Wave

A wave that moves perpendicular to the medium. Ex: UV Rays

Rarefaction

The point in a longitudinal waves where the particles are most spread out. Ex: Quiet part of song

Density

How thick something is. Ex: Steel is denser then oxygen

Crest

Highest point in a wave.

Trough

Lowest point in a wave.
