Across
- 5. image that is seen in a mirror or on a shiny surface
- 8. colours/Primary colors are those that cannot be made from mixing other colors. Instead, primary colors are the source of other colors
- 9. capable of reflecting sufficient undiffused light to form an image of an object placed in front of it (also called looking glass)
- 10. from a straight path undergone by a light ray or energy wave in passing obliquely from one medium (as air) into another (as glass) in which its velocity is different
- 13. arc of spectral colors, usually identified as red, orange, yellow, green, blue, indigo, and violet, that appears in the sky opposite the sun as a result of the refractive dispersion of sunlight in drops of rain or mist
- 17. a surface or boundary that curves or bulges inward
Down
- 1. completely clear or transparent but clear enough to allow light to pass through
- 2. transparent solid body, often having triangular bases, used for dispersing light into a spectrum or for reflecting rays of light
- 3. of light/Not completely clear or transparent but clear enough to allow light to pass through
- 4. spectrum/The entire range of wavelengths or frequencies of electromagnetic radiation extending from gamma rays to the longest radio waves and including visible light
- 6. source/A body that can give off electromagnetic radiation (light)
- 7. rate at which someone or something moves or travels
- 11. to be seen through
- 12. letting light through (opposite of transparent)
- 14. disturbance traveling through a medium by which energy is transferred from one particle of the medium to another without causing any permanent displacement of the medium itself´
- 15. a surface or boundary that curves or bulges outward
- 16. property possessed by an object of producing different sensations on the eye as a result of the way it reflects or emits light:
