Light Waves

2. A beam of light focused in only one direction
5. a clear or translucent material that separates white light into component colors
6. A range of light waves organized by frequency and wavelength
7. Part of the energy that comes from the sun, can burn the skin, and cause skin cancer
11. Has intermediate wavelengths and frequencies near the middle of the electromagnetic spectrum. Helps humans see the world
13. A dark area where light is blocked
14. materials that let some light through and absorbs some light
15. Some of the longest wavelengths and lowest frequencies in the electromagnetic spectrum
17. A range of light waves organized by frequency and wavelength
19. Have very short wavelengths
20. A type of wave that forms an S shape
21. the angle at which a ray of light strikes a surface

1. materials that let light pass through them
3. does not let light pass through
4. The bouncing of light off an object
8. the angle at which a ray “bounces off” a surface
9. The bending of light around barriers or through openings
10. The direction energy is carried as a light wave moves forward
12. Have wavelengths as long as several football fields
16. Make objects visible in dark settings
18. The bending of light as it passes at an angle from one type of matter into another
