1. Final Review
part Two

2. 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

3. Velocity? Force? Acceleration? Maximum displacement Rest position

4. Period of a Pendulum
Changing Variables?

5. 3m 3m
24 m
l?, amplitude? wave speed (given a frequency)?

7. c = lf
c = 3.00 x 108 m/s
solve for l or f

8. Mechanical waves need a medium to travel through
sound: mechanical, transverse, longitudinal, compressional?
pitch vs. frequency
Doppler effect
speeds of sound, light

9. images : real, virtual, magnification
object distance v. image distance
angle of incidence v. reflection
inverse square law

10. image location for a concave mirror
object outside of C, at C, between C and f,
inside of f
image size?

11. Types of images formed by mirrors and lenses

12. index of refraction
which way is light bent?
ray diagrams
