Electromagnetic Spectrum

2. contains all colors of light; only part of the EMS that we can see
4. the color with the longest wavelength on the visible light spectrum
5. high energy, short wavelengths; used for medical applications
6. more energy than microwaves; used for satellite sensors and night vision goggles
9. longest wavelength, lowest energy; used for TV and radio broadcasting
10. a disturbance that transfers energy from point to point
11. the color with the shortest wavelength on the visible light spectrum
12. how we describe the frequency of a wave with long wavelengths and low energy
15. the bending of a wave around barriers or through openings
18. most energy on the EMS; used to treat cancer
19. the distance between two consecutive crests of a wave
20. highest point of a wave

1. shorter wavelengths, greater energy than visible light; small amounts good for you, large amounts dangerous
3. change in direction of a wave due to a change in medium
7. the only color not absorbed by a surface
8. number of waves generated in a given amount of time
13. shorter wavelengths and higher frequency than radio waves; used in microwaves
14. are waves made up of matter or energy
16. how we describe the frequency of a wave with short wavelengths and high energy
17. the abbreviation for the range of radiation arranged in order of frequency
