- Objectives
- After studying the material of this chapter, you should be able to:
- 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.
- Distinguish between a longitudinal wave and a transverse wave and give examples of each type of wave.
- Calculate the speed of longitudinal waves through liquids and solids and the speed of transverse waves in ropes and strings.
- Calculate the energy transmitted by a wave, the power of a wave and the intensity of a wave, across a unit area A.
- 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.
- 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.

How is it that the natural frequency causes an increase in amplitude? When I answered that question on the test, I imagine playing an instrument and thought of using the same amount of air for each note and couldn't understand why a certain note would increase the volume of the sound. Am I just relating it to the wrong thing?
ReplyDeleteFor #28, I get a little box ( __ Hertz ) what is the actual number there?
ReplyDeletei think it is supposed to be "1/60 hertz" because a second hand makes one complete rotation every 60 seconds so in 1 second it makes 1/60 of a rotation.
