Across
- 4. light Relating to electromagnetic radiation with wavelengths shorter than visible light.
- 5. Full range of frequencies of electromagnetic radiation
- 8. lens Spreads light rays apart
- 9. exterior angles Two exterior angles on opposite sides of a transversal which lie on different parallel lines.
- 11. Change in direction of wave propagation due to a change in its transmission medium.
- 12. Smallest unit of light
- 13. light Electromagnetic radiation with longer wavelengths than those of visible light, and is therefore invisible to the human eye.
- 15. lens Focuses light
Down
- 1. The action or process of magnifying something or being magnified, especially visually.
- 2. The rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
- 3. The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.
- 6. angles The angles that occupy the same relative position at each intersection where a straight-line crosses two others.
- 7. Intersecting a system of lines.
- 10. The throwing back by a body or surface of light, heat, or sound without absorbing it.
- 14. A device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation
