(24 cards)

Frequency

Front

The number of oscillations or vibrations per second.

Back

Mechanical

Front

Waves requiring a medium to travel through.

Back

Energy

Front

Increases as amplitude or frequency are increased, decreases as wavelength is increased.

Back

Node

Front

Point of no displacement.

Back

Equilibrium

Front

The resting state of a wave (at points without energy).

Back

De-Broglie

Front

Waves Theory used to describe the particle and energy behaviors of matter and how atoms uniquely emit particular wavelengths of energy.

Back

Crest

Front

Point of maximum positive displacement; corresponds to rarefaction of longitudinal wave.

Back

Period

Front

The number of seconds per wave or oscillation.

Back

2

Front

A wavelength of this harmonic is equal to L.

Back

False

Front

True or False? Waves transfer matter as they transfer energy from one location to another.

Back

5

Front

A wave of this harmonic has a section length of 1/5 of L and a wavelength of 2/5 L.

Back

Amplitude

Front

Half the displacement between a wave's crest and trough.

Back

Transverse

Front

Type of wave having matter displacement perpendicular to direction of energy transfer.

Back

True

Front

True or False? Surface waves consist of longitdinal and transverse waves acting together.

Back

2

Front

The number of complete wavelengths in a fourth harmonic wave.

Back

Speed Up

Front

Mechanical waves do this when encountering denser materials.

Back

Non-Mechanical

Front

Waves not requiring a medium to travel through; all EMR.

Back

Longitudinal

Front

Type of wave having matter displacement in same, parallel, direction to energy transfer.

Back

Pressure

Front

Another name for longitudinal waves; accounts for the compression of particles as a wave transfers energy from one location to another.

Back

2L/ (Harmonic #)

Front

Formula for calculating a harmonic wave with two fixed ends.

Back

Slow Down

Front

Non-mechanical waves do this when encountering denser materials.

Back

Antinode

Front

Point of maximum displacement.

Back

1st Harmonic

Front

The fundamental frequency of a wave.

Back

Trough

Front

Point of maximum negative displacement; corresponds to compression of longitudinal waves.
