  1. Wave Unit Test Review!

  2. Transverse Wave highest Crest: _______ point on a wave. lowest Trough: ______ point on a wave.

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

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

  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 wavesaround 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
