Waves Project

6. the incident ray bouncing back in the same medium after striking the reflecting surface
10. a wave in which the particles of the medium move progressively in the direction of the wave propagation
15. the change in direction of a wave passing from one medium to another caused by its change in speed
16. reflection of light from a surface such that an incident ray is reflected at many angles, rather than at just one angle
18. a wave vibrating at right angles to the direction of its propagation
20. a decrease in the density of something
21. substance or material that carries the wave
22. a wave vibrating in the direction of propagation
24. the pulsation caused by the combination of two waves of slightly different frequencies
25. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is a constant, for the light of a given color and for the given pair of media
26. the spreading of waves around obstacles

1. the apparent difference between the frequency at which sound or light waves leave a source and that at which they reach an observer
2. the entire range of wavelengths or frequencies of electromagnetic radiation extending from gamma rays to the longest radio waves and including visible light
3. a force that squeezes something together
4. wave that is not capable of transmitting its energy through a vacuum
5. relatively large selective response of an object or a system that vibrates in step or phase, with an externally applied oscillatory force
7. the angle of reflection of the light is equal to the angle of incidence and on the opposite side of the normal to the point of incidence
8. property of certain electromagnetic radiations in which the direction and magnitude of the vibrating electric field are related in a specified way
9. the angle of the reflected ray is equal to the angle of the incident ray
11. combination of two waves moving in opposite directions, each having the same amplitude and frequency
12. The sensation of a frequency
13. electromagnetic radiation with a single constant frequency
14. The spectrum seen when incident waves are selectively altered by a reflecting substance
17. regular variation in magnitude or position around a central point.
19. the position of maximum displacement in a standing wave system
23. the positions of continuous zero displacement
