Analyzing Waves
1. The highest point on a wave is the ___crest__, while the lowest point is the __trough___.
2. The distance from one crest to the next crest is the __wavelength___.
3. The _frequency___ is a measure of the number of waves that pass a point in a given amount of time.
4. The illustration to the right shows a wave.
Label each part in the space below:
a. _____crest_______
b. _____trough______
c. ____amplitude____
d. ___wavelength____
5. Use the five illustrations of waves drawn below to answer the following questions:
(a) Waves P and Q have the same _wavelength/frequency__, but wave P has twice the
__amplitude__ of wave Q.
(b) Waves Q and R have the same _amplitude_, but wave R has twice the _wavelength/frequency__
of wave Q.
(c) Wave __T___ shows a steady frequency but changing amplitude.
(d) Wave __S__ shows steady amplitude but a changing frequency.
6. A kid on a playground swing makes 6 complete to-and-fro swings each 30
seconds.
(a) The frequency of the swinging is __6/30 or 0.2 Hz___.
(b) The period of the swinging is __30/6 or .5 sec__.
