B. Period (T) – time for an entire wave cycle to pass a given point in a medium


- determined by source of vibration not medium



T = Total Time/# of waves



Ex) Use the controls to give this wave an amplitude of 5 and a period of 10


Ex) It takes 20 seconds for 5 waves to pass by a point. What is the period?





The period is 4 seconds





(sec) (Period)





Ex) The frequency of a light

wave is 5.0 x 1014 hertz.

What is the period of the wave?


T = 1/f




 = 1/(5.0 x 1014 hertz)



a) 2.0 x 10-15 s





Which has the largest period?

Jan 2004







(will take the
longest  to pass by)





C. Amplitude – maximum change in position of a particle from its rest position during a single vibration

St. Mary's Physics Online


- determined by source of vibration, not medium







Ex) Compare waves A & B






Same Frequency, Period
Different Amplitude




1. Amplitude of a wave shows the amount of energy in the wave




a. Amplitude is a measure of loudness for sound and brightness for color -
