  31. When does Total Internal Reflection (TIR) occur?
  32. Critical Angle when total reflection occur
  33. Mirror Lense equation
  34. focal length
  35. Magnification
  36. Lens power, P =
  37. Lens Magnification, m =
  38. Combination of different lens powers, Ptot =
  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
  45. density of water
    1000kg/m3 = 1g/cm3
  46. ρgwater
    1E4 kg/(m2s2)

    1E3 gm/(cm2s2)
  47. frequency of standing waves, one open end

    what are the possible n's?
    • f = nv/4L
    • n st be muan odd number (1, 3, 5)
  48. Define Intensity of a sound wave
    Energy transmitted per second (Power) per unit area.

    so W/m2
  49. What is the lowest intensity heard by the human hear? the baseline intensity Io?
    1E-12 W/m2
  50. What is the Intensity level (sound level) of a wave of sound wave of intensity I?
    log ( I / I0 )

    • in decibels:
    • dB = 10 log ( I / I0 )
  51. In intensity lebel calculations, how does the intensity level in dB change when I is multiplied or divided by 10?
    • I*10 -> dB + 10
    • I/10 -> dB - 10
  52. In the mirror and lens equation, how do we differentiate a virtual from a real image?
    • real images = + i
    • virtual images = - i
  53. How does the notation for focal length between mirror and lens equations?
    • FOR LENSES:
    • +f converging
    • -f diverging

    • MIRRORS
    • +f concave
    • -f convex
  54. in mirror and lense equation, + i / - i means
    • + i = real image
    • - i = virtual image
  55. in mirrors + (f, i, and o) are where in relation to mirror?
    same side as object
  56. in lenses, + i is where in relation to lense?
    opposite side from object
  57. what does + or - magnification mean?
    • +m = image upright
    • - m = image inverted
