AP WAVES

Day 82 Notes from Class
6. State the conditions necessary for resonance. Give examples of instances where resonance is a) beneficial and b) destructive. Explain how damped harmonic motion can be achieved to prevent destructive resonance.
7. Distinguish between a longitudinal wave and a transverse wave and give examples of each type of wave.
8. Calculate the speed of longitudinal waves through liquids and solids and the speed of transverse waves in ropes and strings.
9. Calculate the energy transmitted by a wave, the power of a wave and the intensity of a wave, across a unit area A.
10. Describe wave reflection from a barrier, refraction as the wave travels from one medium into another, constructive and destructive interference as waves overlap, and diffraction of waves as they pass around an obstacle.
11. Explain how a standing wave can be produced in a string or rope and calculate the harmonic frequencies needed to produce standing waves in string instruments.
