Waves Vocab

3. An object allows some frequencies of visible light to pass through but not others.
5. waves- When a wave shakes to the direction of propagation
7. Something that takes energy from point to point
8. The number of waves that pass a fixed point in unit time
10. A region of the electromagnetic radiation spectrum where wavelengths range from about 700 nanometers to 1 millimeter.
11. Shorter wavelengths than visible light.
14. Measurement of the amount of energy transferred by a wave
15. A portion or “band” found at the higher frequency end of the radio spectrum.
16. Low point of a wave
20. The change in direction of a wave as it passes from one medium to another.
21. The time it takes for two successive crests to pass a specified point.
23. The rate of change of position of an object in any direction
24. waves- A mechanical wave that goes along the interface between media

1. waves- Something that travels through a medium
2. waves- A wave that is created when several variations of magnetic fields and electricity are intense.
3. Materials that allow the transmission of light waves through them
4. A piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light.
6. Does not allow transmission of light waves.
9. The distance between corresponding points of two consecutive waves
12. A transverse wave characterized by alternating magnetic and electric fields propagating perpendicular to the directions of the wave.
13. ray- The smallest wavelengths and the most energy of any wave in the electromagnetic spectrum.
17. A type of electromagnetic radiation with the longest wavelengths in the electromagnetic spectrum.
18. waves- When a wave shakes at right angles
19. A point on a surface wave when the displacement of the medium is at the max
22. The change in direction of a wavefront at an interface between two different media so that the wavefront returns to the medium from which it originated.
