| A | B |
|---|
| wave | carries energy from place to place |
| vibrations | where waves get their energy |
| example of mechanical wave | sound wave |
| wave transmitted through a vacuum | light wave |
| transverse wave | particles move at right angles to wave direction |
| speed = | frequency X wavelength |
| apparent breaking of pencil in water | refraction |
| hearing sound around a corner | diffraction |
| W=2m / F=8 waves/sec | S=16m/s |
| distance between troughs | wavelength |
| Frequency increases in a medium | Speed stays the same |
| waves that meet at the same pt | interference |
| waves transfer | energy |
| frequency is measured in | hertz |
| 30 vibrations in 10 sec | Frequency= 3 Hz |
| highest pts on a wave | crests |
| speed of a wave | does not depend on sped of source |
| 6th period | Advanced science |
| Greater the amplitude | greater the energy amount |
