waves

5. the distance between twp peaks of the wave
6. objects in motion will stay in motion and objects at rest will stay at rest unless acted upon by force
7. a wave that has changed direction by moving from one material to another material of different density
10. a wave of energy consisting of electric and magnetic fields oscillating at right angles to each other
11. waves vibrating forms of energy that are made of molecules and look like waves

1. the transfer of energy in a motion that is perpendicular to the direction the wave is moving
2. force equals mass times acceleration
3. when waves bend around small obstacles or spread out after they pass through small openings
4. a disturbance that transfers energy from one location to another
8. a measure of how big its oscillation is
9. a wave that travels through a material, or fluid, or on its surface without causing permanent structural physical change
