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