  39. Big rule #1 for waves
    • The speed of a wave IS determined by:
    • a. The characteristics of the medium
    • b. The type of wave
    • but it is NOT determined by its frequency.
  40. Big rule #2 for waves
    When a wave passes into another medium, its SPEED changes, but its frequency does not change
  41. In sound, pitch is a function of?
    frequency
  42. in mirror and lens eququation, what does i stand for?
    image distance from the mirror or lens.
  43. in mirror and lens equation, what does m stand for?

    What are its notations?
    lens magnification.

    • +m = image upright
    • -m = image inverted.
  44. in light optics are real images upright or inverted?
    • virtual upright
    • real inverted
