A disturbance that repeats regularly in space and time that transmits energy from one place to another with no transfer of matter.
Wave
The highest point of a transverse wave
Crest

Diffraction
The longest wavelength on the electromagnetic spectrum
Radio waves
The measurement on a transverse wave from one crest to the next.
Wavelength
A wave in which the motion of the material is parallel to the direction that the energy travels.
Longitudinal
The area of a longitudinal wave where the particles are farthest spread apart
Rarefaction

Refraction
The shortest wavelengths on the electromagnetic spectrum
Gamma rays
The measurement from the point of rest to the crest - measures the amount of energy a wave is carrying.
Amplitude
A wave in which the motion of the material is perpendicular to the direction that the energy travels
Transverse
The lowest point on a transverse wave
Trough

The red, orange, yellow, blue, violet and indigo wavelengths
Absorption
The portion of the electromagnetic spectrum that we can see
Visible light
The measurement of how many waves pass a given point in one second.
Frequency
A behavior in which a wave passes through a given point or medium.
Transmission
The area of a longitudinal wave where the particles are closest together
Compression

The green wavelengths
Reflection
The portion of the electromagnetic spectrum found between microwaves and visible light.
Short wavelength = __________ frequency
The volume of a sound or a measurement of how strong the sound is
Intensity
The midpoint of a wave
Resting position or point of rest

The blue wavelengths
Scattering
The portion of the electromagnetic spectrum found between ultraviolet and gamma rays.
X-rays
The measurement of a longitudinal wave from one compression to the next.
