14.9: Thinking about the material

  • Page ID
  • Reflect and research

    1. Look up a video of the Tacoma Narrows bridge failing, and explain what happened.
    2. Why do airlines ask you to turn off your electronic devices during take-off?
    3. Is it true that there is no sound in space?
    4. What type of wave was first observed in 2015?

    To try at home

    1. Confirm that the reflected pulse from a rope on a string is inverted when the end of the rope is fixed.
    2. Think of different ways you could create a standing wave at home and try one of them out. How many harmonics can you create? How can you modify your set-up to create more harmonics?

    To try in the lab

    1. Propose an experiment to verify the relation \(v=\lambda f\).
    2. Propose an experiment which uses diffraction to measure small distances.
    3. Propose an experiment to determine the chemical composition of the sun using a CD.
    4. Design a device which acts as a echolocator and test its effectiveness in different scenarios.
    5. Propose an experiment to observe triboluminescent x-rays produced by ripping scotch tape off of a surface.
    6. Investigate and model refraction.
    7. Investigate and model the doppler effect.
    8. Investigate and model how standing waves behave on a stretched string, tube, or 2D medium.
    9. Investigate and model audible beats.
    10. Investigate and model double-slit interference.
