|---|---|---|---|
|
What is a wavelength?
Distance from middle of one crest/compression to middle of the next crest/compression.
|
What is transverse and longitudinal wave?
The two different kinds of waves.
|
What is a longitudinal wave?
Type of wave has vibrations parallel to the motion of the wave.
|
What is oscillation?
The side to side swinging of a pendulum is an example of this.
|
|
What is the crest?
Highest point of the wave.
|
What is light?
Acts as a transverse wave.
|
What is a transverse wave?
Type of wave has vibrations that are perpendicular to the motion of the wave?
|
What is a rarefaction?
Opposite of a compression.
|
|
What is a trough?
Lowest point of the wave.
|
What is sound?
Acts as a longitudinal wave.
|
What is a period?
Time to complete a single cycle.
|
What is hertz?
Equals the number of cycles per second.
|
|
What is a compression?
When there is a high frequency and the waves are close together.
|
What is amplitude?
Distance from the resting line to the top of the crest and/or the bottom of a trough.
|
What is hertz?
Unit for frequency.
|
What is the speed of light?
Moves at 299 792 458 m / s.
|
|
What is a rarefaction?
When there is a low frequency and the wavelength is more spaced out.
|
What is oscillation?
Movement back and forth.
|
What is period?
Represented by the capital letter T.
|
What is the speed of sound?
Moves at 331.5 m/s.
