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