Review of waves vocabulary

2. _______ point on a wave.
______ point on a wave.
highest
lowest

3. Transverse waves are known as:
ELECTROMAGNETIC WAVES
-Visible light
-Gamma rays
-Microwaves
-Radio waves
-X rays

4. ____________ parts of the wave.
_________ parts of the wave.
Compression:
Rarefaction:
Tightly packed
Spread out

5. Longitudinal waves are known as:
How do sound waves travel?
SOUND WAVES
Sound is produced by
vibrations in a medium.

6. What is a MEDIUM?
A substance that a wave travels through!
What are the 3 mediums that sound
can travel through?
1. SOLID 2. LIQUID 3. GAS

7. What is the BEST medium for
transferring sound waves?
SOLID
Since its molecules are tightly
packed together, they can transfer
the energy easily and quickly!

8. Amplitude:
how large a wave is

9. Wavelength:
how long a wave is, from crest to
crest

10. Frequency:
The number of waves produced in
a certain amount of time.

11. Period = Frequency/Time
Sound waves are produced by a
guitar and 16 waves are measured in
2 seconds. What is the period?
Period= 16 waves/2 seconds
Period= 8 waves/sec.

12. Pitch vs. Loudness
The PITCH of a sound is
determined by the frequency of a
sound wave.

13. Pitch vs. Loudness
The LOUDNESS of a sound is
determined by the amplitude of a
sound wave.

14. What is the Doppler Effect?
The sound waves IN FRONT of the
object are packed together and loud,
while the waves BEHIND the object
are stretched out and quiet!

15. Reflection:
The bouncing back of a wave after it
strikes a barrier.

16. Diffraction:
The bending of waves around
barriers and through openings.

17. Interference:
The result of two or more waves
overlapping.

18. Resonance:
Occurs when an object vibrating
causes a second object to vibrate.

19. Refraction:
The bending of a wave as it passes at
an angle from one medium to another.

20. Absorption:
The transfer of energy carried by
light waves to particles of matter.
Example:
-Greenhouse
-wearing dark
colors
