  2. White light passing through a prism separates into colors because of the differences in the _______ of each color of light.

  3. Wavelength or frequency

  4. Waves in a rope are transverse waves because the medium’s vibration is __________ to the direction in which the wave travels.

  5. perpendicular

  6. Consider a wave approaching a barrier with a small hole. What change is the wave likely to undergo as it encounters the barrier.

  7. Diffraction

  8. Two waves in the ocean meet and combine together. This interference is described as.

  9. What is constructive interference?

  10. The formula for wavespeed.

  11. Wave speed = Frequency x wavelength.

  12. The basic difference between electromagnetic waves and sound waves.

  13. EM waves do not require a medium while Sound waves do.

  14. Electromagnetic waves vary in

  15. Frequency and wavelength

  16. A translucent material does this with light.

  17. Scatters some light.

  18. When viewed in blue light, an object that reelects all the colors of light will appear _______

  19. Blue

  20. What does light passing through a prism prove?

  21. White light is made of all colors.

  22. Name three ways that charge can be transferred.

  23. Induction, contact, friction

  24. What is the difference between direct current and alternating current.

  25. In direct current charges only flow in one direction, in alternating it can travel in two directions.

  26. The current in a toaster oven measures 10 amps. The resistance of the iron is 12 ohms. Find the voltage.

  27. V=IRV = 10amps x 12 ohmsV = 120 Volts

  28. The voltage is 90 volts and the resistance is 30 ohms of an object. Find the current.

  29. V = IRI = V/RI = 90volts/30ohmsI = 3 Amps

  30. Name three things that affect resistance.

  31. Thickness, length, and temperature.

  32. The type of current used in your house.

  33. Alternating Current (AC)

  34. Type of transfer of charge when putting your hand near a Van de Graff generator.

  35. Induction

  36. A person walks 6 meters forward, realizes he drops his keys and walks back 3 meters to get them. What is his displacement?What is the distance traveled?

  37. Displacement = 3mDistance = 9m

  38. Describe Newton’s laws of motion.

  39. 1st = Inertia2nd is F=MA3rd = For every action there is an equal and opposite reaction.

  40. Describe refraction.

  41. Light has the ability to bend, or refract, as it enters a new medium

  42. 2008 Superbowl Champions

  43. New York Giants

  44. Who said, "Imagination is more important than knowledge."

  45. Albert Einstein

  46. P waves in an Earthquake travel as what?

  47. A series of compressions and rarefactions.

  48. Name the two things that affect the strength of an electric field.

  49. Amount of charge on the object and distance from the charge.

  50. A car moves at 20m/s, 10 s later the car is moving at 50 m/s. Find the cars acceleration.
