Reflect and research
- Look up a video of the Tacoma Narrows bridge failing, and explain what happened.
- Why do airlines ask you to turn off your electronic devices during take-off?
- Is it true that there is no sound in space?
- What type of wave was first observed in 2015?
To try at home
- Confirm that the reflected pulse from a rope on a string is inverted when the end of the rope is fixed.
- 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
- Propose an experiment to verify the relation \(v=\lambda f\).
- Propose an experiment which uses diffraction to measure small distances.
- Propose an experiment to determine the chemical composition of the sun using a CD.
- Design a device which acts as a echolocator and test its effectiveness in different scenarios.
- Propose an experiment to observe triboluminescent x-rays produced by ripping scotch tape off of a surface.
- Investigate and model refraction.
- Investigate and model the doppler effect.
- Investigate and model how standing waves behave on a stretched string, tube, or 2D medium.
- Investigate and model audible beats.
- Investigate and model double-slit interference.
