TIPS:

1) You need to understand that for transverse waves, the oscillations are perpendicular to the

direction of energy transfer, ut in a longitudinal wave, the oscillations are parallel to the

direction of energy transfer!

") #aves are ale to transfer energy, this ties in to the concept of radiation we discussed last

wee$!

%) & wave usually involves a periodic and repetitive movement!

Displacement-Time Graps

'here are some asic descriptors of a wave!

#avelength is distance etween an identical part of the wave!

&mplitude is ma(imum displacement from neutral position! 'his represents the energy

of the wave! reater amplitude e*uates to greater energy!

Displacement is the position of a particular point in the medium as it moves as the wave

 passes! +a(imum displacement is the amplitude of the wave!

re*uency -.) is the numer of repetitions per second in /0, s 1

Period -') is the time for one wavelength to pass a point!

'he velocity -v) of the wave is the speed that a specific part of the wave passes a point! 'he

speed of a light wave is c!
