Energy in the form of the random movement of atoms, also know as heat.
a) Reflection
b) Absorption
c) Transmission
d) Thermal Energy

When a wave goes between to types of matter, and the wave is able to pass through the second type. Think fiber optics, stethoscopes, cars in a tunnel...
a) Reflection
b) Absorption
c) Transmission
d) Thermal Energy

When a wave goes between to types of matter, and the wave goes into the second matter and leaves the energy as heat. Think sun tanning, sound proofing...
a) Reflection
b) Absorption
c) Transmission
d) Thermal Energy

Any oscillation that moves energy from one point to another.
a) Wave
b) Amplitude
c) Wavelength
d) Crest

The height of a transverse wave, or the difference in pressure between the compression and rest in a longitudinal wave
a) Wave
b) Amplitude
c) Wavelength
d) Crest

The distance between two crests in a wave. The larger this is, the lower the frequency, i.e. more red light, lower pitch sound.
a) Wave
b) Amplitude
c) Wavelength
d) Crest

The highest point on a wave
a) Wave
b) Amplitude
c) Wavelength
d) Crest

The lowest point on a wave
a) Trough
b) Longitudinal Wave
c) Transverse Wave
d) Frequency

Pressure waves that move back and forth in line with energy transfer, such as sound
a) Trough
b) Longitudinal Wave
c) Transverse Wave
d) Frequency

Side to side waves, such as light
a) Trough
b) Longitudinal Wave
c) Transverse Wave
d) Frequency

The number of oscillations or cycles per second. More of this is bluer light, higher pitch.
a) Trough
b) Longitudinal Wave
c) Transverse Wave
d) Frequency

Transvers waves that are caused by energy switching back and forth between electricity and magnetism.
a) Light Wave
b) Sound Wave
c) Pressure
d) Oscillation

Longitudinal waves caused by pressure moving atom to and fro, inline with the motion of the energy.
a) Light Wave
b) Sound Wave
c) Pressure
d) Oscillation

How much atoms are being pushed together
a) Light Wave
b) Sound Wave
c) Pressure
d) Oscillation

any repeating pattern where something goes back and forth, like a swing.
a) Light Wave
b) Sound Wave
c) Pressure
d) Oscillation

When a wave goes between to types of matter, and the wave bounces off of the second type. Think echo, mirror...
a) Reflection
b) Absorption
c) Transmission
d) Thermal Energy
