Across
- 1. spreading of waves as they pass through or around an obstacle.
- 4. complete range of all types of radiation that has both electric and magnetic fields and travels in waves.
- 7. change in the direction of propagation of a wave that strikes the boundary between different mediums.
- 9. measured distance between two identical points on two back-to-back waves.
- 10. change in wave frequency during the relative motion between a wave source and its observer
- 11. material that moves energy or light from one substance to another, or from one location to another, or from one surface to another
- 13. displacement of the medium is in the same direction as the direction of the travelling wave.
- 15. the bending of light and other waves.
Down
- 2. when two waves overlap in such a way that they combine to create a larger wave
- 3. the maximum displacement or distance moved by a point on a vibrating body
- 5. waves come together so that they completely cancel each other out
- 6. distance the wave travels in a given amount of time
- 8. radiation electric and magnetic disturbance traveling through space at the speed of light
- 12. number of waves that pass a fixed point in a given amount of time
- 14. motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
