Across
- 2. a wave whose oscillations are perpendicular to the direction of the wave's advance
- 5. the rate at which something occurs or is repeated over a particular period of time or in a given sample
- 6. the lowest frequency of a periodic waveform
- 9. an increase (or decrease) in the frequency of sound, light, or other waves as the source and observer move toward (or away from) each other
- 10. phenomenon of light, radio waves, etc. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density
- 13. segment of one cycle of a longitudinal wave during its travel or motion, the other segment being compression
- 14. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
- 15. the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium
- 16. a force that squeezes something together
- 17. a wave vibrating in the direction of propagation
Down
- 1. is an oscillation of matter, and therefore transfers energy through a medium
- 3. phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude
- 4. waves that are created as a result of vibrations between an electric field and a magnetic field
- 7. the quality or state of being intense especially
- 8. A substance that makes possible the transfer of energy from one location to another, especially through waves
- 11. is the subjective perception of sound pressure
- 12. a disturbance that moves energy from one place to another
- 18. the process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture
