Electromagnetic Spectrum
Across
- 3. The specific wavelength and frequency of light that is released unique to the elements present.
- 7. The second-lowest energy wave on the EMS. Uses include heating food in a microwave oven.
- 9. Color created by mixing/adding visible light primary colors: green, blue, red.
- 10. A low energy and frequency electromagnetic wave. Its long wavelength makes it useful for radio, television, or radar communication.
- 11. The only electromagnetic waves humans can see (rainbow).
Down
- 1. Color created when light is removed.
- 2. Any of a group of colors from which all other colors can be obtained by mixing.
- 4. All EMS waves move at this speed.
- 5. A particle with energy and movement but no mass or charge.
- 6. These waves have a higher energy and frequency than microwaves but lower than visible light.
- 8. Beyond the visible spectrum at its violet end. Relating to, producing, or employing ultraviolet radiation.
