when a vibration (or back and forth motion) moves through a space

• amplitude

• trough

• wave

• mechanical wave

is how many waves pass by per unit of time. It is measured in Hz or Cycles per Second.

• frequency

• trough

• wave

• mechanical wave

is the type of material that a wave travels through. It can be water, air, metal or any other material.

• frequency

• trough

• medium

• mechanical wave

is the very top of the wave. One wavelength is measured from peak to the next peak.

• frequency

• electromagnetic wave

• medium

• peak or crest

Is the length of one wave. It is measured from peak to peak. It is a distance measured in meters.

• simple harmonic motion

• electromagnetic wave

• wavelength

• peak or crest

is when a wave hits a surface and bounces off.

• simple harmonic motion

• wave velocity

• reflection

• peak or crest

is how long it takes a wave to complete one cycle. It is measured in seconds, minutes, or hours.
