Waves Sound & Light

Waves TEST Due Monday


  • 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.

WORK ENERGY POWER TEST
Work Defined
Energy Video

Objectives

After studying the material of this chapter, you should be able to:
1. Distinguish between work in the scientific sense as compared to the colloquial sense.
2. Write the definition of work in terms of force and displacement and calculate the work done by a constant force when the force and displacement vectors are at an angle.
3. Use graphical analysis to calculate the work done by a force that varies in magnitude.
4. Define each type of mechanical energy and give examples of types of energy that are not mechanical.
5. State the work energy theorem and apply the theorem to solve problems.
6. Distinguish between a conservative and a nonconservative force and give examples of each type of force.
7. State the law of conservation of energy and apply the law to problems involving mechanical energy.
8. Define power in the scientific sense and solve problems involving work and power.
