  7. DAILY DOUBLE A range of wavelengths in the electromagnetic spectrum that we can see. (Name what you can see)

  8. DAILY DOUBLE What is the visible spectrum of light (red, orange, yellow, green, blue, indigo, violet)?

  9. A technique that scientists use to separate substances to study them.

  10. What is chromatography?

  11. The highest point in a wavelength is called the____________.

  12. What is the crest?

  13. A ____________ is a substance that allows only certain colors of light to pass through it.

  14. What is a filter?

  15. If there is _______________, it is caused by the bending of light as it moves from one material to another.

  16. What is refraction?

  17. DAILY DOUBLE The lowest part of a wavelength is referred to as a ___________.

  18. DAILY DOUBLE What is a trough?

  19. A solid, transparent object that refracts light passing through- separating the light into the colors of the visible spectrum is called a ___________.

  20. What is a prism?

  21. What are the primary colors of light?

  22. Red, blue and green.

  23. Magenta, Cyan and yellow.

  24. What are the primary colors of pigment?

  25. The distance from one wave crest to the next.

  26. What is the wavelength?

  27. DAILY DOUBLE When light bends as it passes through air at different temperatures, we can see one of these.

  28. DAILY DOUBLE What is a mirage?

  29. Light from a light bulb, flashlight, or the sun is referred to as this.

  30. What is white light?

  31. Letter D?

  32. What is the optic nerve?

  33. Letter B

  34. What is the lens?

  35. Letter E

  36. What is the pupil?

  37. Letter C

  38. What is the retina?

  39. Letter F

  40. What is the cornea?

  41. Letter A

  42. What is the iris?

  43. DAILY DOUBLE Name at least three surfaces that reflect light.

  44. DAILY DOUBLE Will accept any of the following: water, glass, metal.

  45. DAILY DOUBLE Explain why when light shines on an apple, we see that it is red and no other color.

  46. DAILY DOUBLE We see red because the apple reflects only wavelengths of red light and absorbs all other colors.

  47. Other than visible light, name one other type of ray in the electromagnetic spectrum.

  48. What is: X-rays, gamma rays, infrared rays, radio waves, microwaves.

  49. What makes an object appear black or white?
