|---|---|---|---|---|---|
| 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
🗑
|
||||
