Name: __
1. – 3. Define and draw a picture of a transverse wave (how do the particles move?).
Give an example of a transverse wave.
Particles move
perpendicular to
the wave
(energy). Light is
an example. P
waves
(earthquakes) re another.
4. – 6. Define and draw a picture of a longitudinal wave (how do the particles move?).
Give an example of a longitudinal wave.
Particles move parallel
to the wave (energy).
Sound is an example.
S waves
(earthquakes) are
another.
Define the following terms, then label them on your diagrams above:
7. crest:
highest point on a wave
8. trough:
lowest point on a wave
“size” of a wave: crest/crest or
trough/trough or compression/compression
or rarefaction/rarefaction or
one point to same point on next wave
10. amplitude: “height” of a wave…maximum
9. wavelength:
11. period:
displacement
time for one wave (sec.)
12. frequency:
number of waves per second (Hz)
13. compression:
14. rarefaction:
where waves “bunched” together
where waves are spread out
15. Waves bounce back when they meet a surface. This phenomenon is called…
Reflection (how mirrors work)
16. Waves “bend” as they go around an object. This phenomenon is called…
Diffraction (why we can hear sound from
another room)
17. Waves “bend” as they go from 1 medium to another. This phenomenon is called…
Refraction (how lenses work)
18. – 19. When waves bounce back on each other, they sometimes add together and
amplitude increases. This phenomenon is called…(draw it)
constructive interference
20. - 21.When waves bounce back on each other, they sometimes subtract from each
together and amplitude decreases. This phenomenon is called… (draw it)
destructive interference
22. – 23. Waves that occur from bouncing back and appear to be flip-flopping are
called… (draw one with a frequency of 2 Hz)
standing waves
