  1. Mirrors and Lenses Miss Friend

  2. What type of mirror causes beams of light to spread apart?

  3. diverging mirror

  4. What type of mirror causes beams of light to Come together?

  5. Converging mirror

  6. The image below shows what kind of mirror reflecting light?

  7. flat mirror

  8. What happens when parallel beams of light strike a converging mirror?

  9. They all reflect to a single focal point.

  10. True or False?Reflected images can vary in many ways from the actual object.

  11. true

  12. True or false? Reflected images always look exactly like the object they are reflecting.

  13. false

  14. True or false? Reflected images are always virtual images.

  15. false

  16. True or false: a converging lens is often concave on both sides

  17. False

  18. True or false: A converging Lens focuses a parallel beam to a point

  19. true

  20. True or false: A converging lens causes a parallel beam to spread out

  21. false

  22. A ray of light hits a mirror at a 45 degree angle, to what degree will the light reflect?

  23. 45 degrees

  24. A ray of light hits a mirror at a 90 degree angle, to what degree will the light reflect?

  25. 90 degrees

  26. A convex mirror is also known as what kind of mirror?

  27. Diverging mirror

  28. A concave mirror is also known as what kind of mirror?

  29. converging

  30. An object is placed several feet in front of a diverging mirror. The object is then moved closer and closer to the mirror. What will happen to the image size and location as the object moves closer to the mirror?

  31. The image size will increase, and the image location will move closer to the mirror.

  32. Give an example of a time when a diverging mirror could be used:

  33. showing a wider view of a narrow, dangerous intersection

  34. Name three main shapes that mirrors can have.

  35. flat, convex, concave.

  36. Compare and contrast a diverging and a converging mirror.

  37. A converging mirror has a concave shape and causes a parallel beam of light to converge, or come together. A diverging mirror has a convex shape and causes a parallel beam of light to diverge, or spread apart. A real image forms where light from the object converges and actually passes through the image. A real image forms from a real focus in front of a concave mirror. A virtual image is an image from which light appears to diverge. A virtual image seems to be behind a flat mirror.Converging lenses are used for magnifying mirrors, telescopes, microscopes, binoculars, cameras, and projectors.

  38. Explain the difference between a virtual image and a real image

  39. Real image: an image formed on the same side of the mirror; light actually passes through the imageExample: A movie shown on a screen is a real image because light from the projector hits the screen to show the imagevirtual image: an image formed where light does not actually reachExample: A flat mirror can produce a virtual image when an object appears to be behind the mirror though it is actually in front of the mirror
