Final Review part Two
Waves A transfer of energy Frequency How often something happens Cycles or vibrations per time Hz Period How long it takes for one cycle s Period = Frequency-1
Velocity? Force? Acceleration? Maximum displacement Rest position
Period of a Pendulum Changing Variables?
3m 3m 24 m l?, amplitude? wave speed (given a frequency)?
c = lf c = 3.00 x 108 m/s solve for l or f
Mechanical waves need a medium to travel through sound: mechanical, transverse, longitudinal, compressional? pitch vs. frequency Doppler effect speeds of sound, light
images : real, virtual, magnification object distance v. image distance angle of incidence v. reflection inverse square law
image location for a concave mirror object outside of C, at C, between C and f, inside of f image size?
Types of images formed by mirrors and lenses
index of refraction which way is light bent? ray diagrams
