Unit 8: Waves

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

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
