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
T = 1/f
= 1/(5.0 x 1014 hertz)
a) 2.0 x 10-15 s
Which has the largest period?
Jan 2004
B
C. Amplitude – maximum change in position of a particle from its rest position during a single vibration
[ HTML5 ]
- determined by source of vibration, not medium
Ex) Compare waves A & B
Same Frequency, Period
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 -
