6F40.10 – Rayleigh scattering
This demonstration shows the behavior of sunset through Rayleigh scattering. It is a clear way to demonstrate the behavior of light in the atmosphere and gain student’s interest.
Oscillations and Waves
3A70.36 – Simple double pendulum
This demonstration shows chaotic motion using a double pendulum.
3B22.32 – Wave Apparatus
This demonstration illustrates wave propagation.
3D40.19-2 – Musical Saw
This demonstration illustrates resonance in a solid.
3D40.30 – Chladni Plates
This demonstration illustrates vibrational modes in a rigid surface at a frequency generated by the violin bow.
3A70.10 – Wilberforce Pendulum
This demonstration illustrates different oscillation modes for a coupled mechanical oscillator. The pendulum will show alternating vertical and rotational motion.
3B10.20 – Slinky Wave Demo
This demonstration illustrates various wave phenomena using a slinky.
1D52.40 – Rotating Candle
This demonstration illustrates centrifugal force acting on a candle flame.
3D30.16 – Resonance Tubes with Sliding Piston
This demonstration illustrates resonance of sound waves in a tube of varying length.
3C55.35 – Beating/Tuning Forks
The experiment shows how 2 oscillators with slightly different frequencies will drift in and out of phase in a process called “beating”. The frequency of this beating is the difference between the frequencies of the 2 oscillators. If the difference is very large, a “difference tone” might be observed, where the beating becomes fast enough to be heard as a 3rd tone, but this experiment is not able to create such a tone.
