The wave shows:

wave particles moving at a perpendicular to the wave energy

A mechanical wave moves through a medium, which can be:

gas, liquid, solid, or plasma

Transverse and longitudinal waves both…

transfer energy through a medium

Which type of mechanical wave needs a source of energy to produce it?

transverse waves, longitudinal waves, and surface waves

Which waves cause the medium to vibrate only in a direction parallel to the wave’s motion?

longitudinal wave

surface wave

To determine the speed of a wave, you would use which formula?

speed= wavelength x frequency

To find amplitude, measure…

trough to rest pint

crest to rest point

To what is amplitude related?

the amount of energy carried by the wave
