Across
- 2. the max distance that the particles of a wave's medium vibrate from their rest position
- 5. a wave that consists of oscillating electric and magnetic fields, which radiate outward at the speed of light
- 10. a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling
- 12. the highest point of a wave
- 13. interference a superposition of several waves that produce an intensity equal to the differnece of the intensities of the individual waves
- 14. the number of cycles or vibrations per unit of time; also the number of waves produced in a given amount of time
- 15. the distance from any point on a wave to an identical point on the next wave
- 16. waves a pattern of vibration that stimulates a wave that is standing still
- 17. an observed change in the frequency of a wave when the source or observer is moving
- 19. a physical environmental in which phenomena occur
Down
- 1. a wave in which the patciles of the medium vibrate parallel to the direction of wave motion
- 3. a change in the direction of a wave when the wave finds an obstacle such as an opening
- 4. a wave that requires a medium through which to travel
- 6. waves a superposition of several waves that produce an intensity equal to the sum of the intensities of the individual waves
- 7. the time that it takes a complete cycle or wave oscillation to occur
- 8. the bending of a wave front as the wave front passes between two substances in which the speed of the wave differs
- 9. the combination of several waves that result in a single wave
- 11. the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through
- 18. the lowest point of a wave
