Question | Answer |
Frequency of a wave-- | the number of waves that pass through a certain point in a specific amt. of time |
more force = | more amplitude |
Crest-- | high point or peak of a wave |
Amplitude-- | gives indication of how much energy wave has |
Wave-- | a traveling disturbance that ..carries energy.. from one place to another |
A wave is only ______; it's not ______. | energy; matter |
Every wave starts w/ ________ | a vibration |
a vibration-- | any motion that follows the same path repeatedly |
Medium-- | the matter through which the wave is transmitted |
What are the 2 ...kinds... of waves? | Mechanical & Electromagnetic |
Describe Mechanical waves. | require a medium; ex.: sound wave, earthquake wave, water wave |
Describe Electromagnetic waves. | don't require a medium; can travel through a vacuum; disturb electric + magnetic fields but can also travel through solid, liquid, or gas |
Which kind of wave requires a medium? | mechanical |
Which kind of wave doesn't require a medium? | electromagnetic |
List the three ...types... of waves. | transverse, longitudinal,+ surface |
Transverse wave-- | the motion of the medium is perpendicular to the motion of the wave |
Transverse wave-- | example: light wave (type of wave) |
Longitudinal wave-- | motion of the medium is parallel to the direction of the wave |
Longitudinal wave-- | example: sound wave (type of wave) |
the fastest speed known to man @ this point in time | the speed of light in a vacuum |
Which kind of wave can travel through a vacuum? | electromagnetic |
Which kind of wave disturbs electric and magnetic fields? | electromagnetic |
