  1. 5. When light hits an object with this physical property, it gets bounced off.
  2. 8. A type of mirror which has reflecting surfaces that curve inward.
  3. 9. A type of wave that is created by lasers.
  4. 10. Light that is created instantly due to ultraviolet light being absorbed.
  5. 11. A form of radiation that can be used to burn holes in steel.
  6. 13. Light that is created due to high temperature.
  7. 15. Produces its own light.

  1. 1. The production of light due to a chemical reaction.
  2. 2. When light hits an object with this physical property, it is absorbed.
  3. 3. A type of mirror that has a flat and reflective surface.
  4. 4. The process in which light is produced from ultraviolet light. This results in a light which becomes visible over time.
  5. 5. The element neon glows this colour when an electric current is passed through it.
  6. 6. When light hits an object with this physical property, it passes through.
  7. 7. A type of image that is created from rays which seem to be coming from a position that they actually are not.
  8. 12. The production of light in living organisms due to a chemical reaction.
  9. 14. The element helium glows this colour when an electric current is passed through it.
  10. 17. A type of image that is created when reflected rays meet.
