Across
- 2. a concave lens is any lens that has an inward curve in the middle. In other words, the edges of the lens are thicker than the middle
- 3. the action or process of magnifying something or being magnified, especially visually
- 6. the range of wavelengths or frequencies over which electromagnetic radiation extends
- 8. intersecting a system of lines
- 9. the throwing back by a body or surface of light, heat, or sound without absorbing it
- 10. a particle representing a quantum of light or other electromagnetic radiation, photons carry energy proportional to the radiation frequency but has zero rest mass
- 13. electromagnetic radiation with wavelengths shorter than visible light
- 14. being deflected in passing obliquely through the interface between one medium and another or through a medium of varying density
Down
- 1. the angles that occupy the same relative position at each intersection where a straight line crosses two others
- 4. the distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
- 5. a convex lens bends light rays inward, which results in the object being perceived as larger or closer
- 7. exterior angles on opposite sides of a transversal which lie on different parallel lines
- 11. the rate at which a vibration occurs that constitutes a wave, either in a material, or in an electromagnetic field
- 12. a device that generates an intense beam of coherent monochromatic light by stimulated emission of photons from excited atoms or molecules
