| 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 |
