Across
- 2. the rate at which a wave propagates or travels through a medium
- 5. the set of waves of an electromagnetic field, which propagate through space and carry momentum
- 6. a wave where the particles of the medium vibrate back and forth in the same direction the wave travels
- 8. distance between corresponding points of two consecutive waves
- 10. the spreading of waves around obstacles
- 12. occurs when two or more waves combine in such a way that their crests and troughs align
- 14. the substance or material through which a wave travels
- 15. the change in the frequency of a wave in relation to an observer who is moving
Down
- 1. occurs when two or more waves overlap in such a way that their amplitudes cancel each other out
- 3. a measurement of the amount of energy transferred by a wave
- 4. a wave vibrating at right angles to the direction of its propagation
- 7. the change in direction of a wave passing from one medium to another
- 9. the range of wavelengths or frequencies over which electromagnetic radiation extends
- 11. how often something happens or repeats within a given time period
- 13. abrupt change in the direction of propagation of a wave
