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
58. mnemonic for electromagnetic spectrum from lowest to highest frequency
• Real Men Induce Very Unusual seX Games
• Radio waves, Microwaves, Infrared, Visible light, Ultraviolet, X-rays, Gamma-rays
