Across
- 3. wave a wave that is an oscillation of matter, and therefore transfers energy through a medium
- 6. the change in direction of a wave passing from one medium to another caused by its change in speed
- 8. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
- 11. wave waves of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays
- 13. wave a wave vibrating in the direction of propagation
- 14. maximum value of upward displacement within a cycle
- 17. waves pass through a given point or medium
- 18. the rate at which something occurs or is repeated over a particular period of time or in a given sample.
- 19. a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter
- 20. the transfer of the energy of a wave to matter as the wave passes through it
Down
- 1. opposite of a crest, so the minimum or lowest point in a cycle
- 2. the process by which wave energy spreads perpendicularly to the dominant direction of wave propagation
- 4. interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude.
- 5. reduction of an item's density, the opposite of compression
- 7. a periodic variable is a measure of its change in a single period
- 9. abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums
- 10. the intervening substance through which impressions are conveyed to the senses or a force acts on objects at a distance
- 12. a region in a longitudinal (sound) wave where the particles are closest together
- 15. for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected
- 16. wave a wave vibrating at right angles to the direction of its propagation
