LIGHT ONE MR. G.
VA 5th GRADE LIGHT MR. G. 878562 mles
| Question | Answer |
|---|---|
| 1. visible spectrum (espectro visible) | The part of the electromagnetic spectrum that humans can see, ROYGBIV, of course Superman may be able to see other frequencies on the electromagnetic spectrum |
| 2. reflection (reflexión) | when light bounces off a surface |
| 3. refraction (refracción) | when light enters or exits a medium at an angle it bends because of a change in speed |
| 4. opaque (opaco) | no light can pass through; light is reflected or absorbed |
| 5. transparent (transparente) | light is transmitted through; the object is clear |
| 6. translucent (translúcido) | some light is transmitted, some is absorbed and some is scattered- example, wax paper |
| 7. wavelength (longitud de onda) | on a wave, the distance from crest to crest or trough to trough |
| 8. crest (cresta) | the top or highest part of a wave. |
| 9. trough | the bottom of a wave |
| 10. medium | solids, liquids and gases |
| 11.electromagnetic spectrum (espectro electromágnetico) | Electrical and magnetic energies including, radio & TV waves, microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays (ordered longest to shortest wavelengths) |
| 12. ROYGBIV | acronym for the colors of the rainbow (visible spectrum): Red, Orange, Yellow, Green, Blue, Indigo and Violet in order from LONGEST to SHORTEST |
| 13. convex (convexo) | a surface that is curved outward (light waves become focused) |
| 14. concave (cóncavo) | a surface that is curved inward (light waves are spread out) |
| 15. lens (lente) | a curved piece of transparent material used to refract light |
| 16. mirror (espejo) | a smooth, very reflective surface, reflected images are reversed |
| 17. absorb (absorba) | to take in or swallow up (rather than transmit or reflect) |
| 18. transmit (transmita) | to go through |
| 19. X-rays, radio waves, microwaves, gamma rays, etc. | energy on the electromagnetic spectrum that humans can not see - perhaps Superman can! |
| 20. prism (prisma) | A triangular shape lens that refracts white light in to its component part - ROYGBIV, the visible spectrum or colors of the rainbow - rains drops can act like prism and create rainbows (but not pots of gold!) |
| 21. Sir Issac Newton | Proved white light was actually all the colors of the spectrum, coined the term spectrum meaning ghostly image - he lived in the mid 1600's and early 1700's and was a member of the Royal Society |
| 22. Galileo | The first person to use a telescope to study astronomy in depth - he supported the theory that the sun is the center of our solar system and therefore was placed under house arrest by the Church |
| 23. Anton Van Leeuwenhoek | A Dutch man that ground lenses as hobby (he was a haberdasher) made the first useable microscope - first to see single cells organisms - joined the Royal Society |
| 24. Robert Hooke | Using a microscope he described "little boxes" or cells |
| 25. Particle and Wave Models | Two models of light scientists use to explain its properties, characteristics, and behaviors |
| 26. Light waves are transverse. (Sound is a longitudinal wave.) | What type of waves are light? Copyright © 2012 S Gissendanner Free for personal and classroom use |
