5B20.30 – Faraday’s cage – electroscope
With this demonstration we can better visualize how the faraday’s cage works and why it works.
7A10.32 – Photoelectric Effect Stopping Potential
This demonstration illustrates the wavelength dependency of the stopping potential, and can also be used to show it is independent of the light source intensity.
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.
5D20.10 – Temperature Dependence of Resistance
This demonstration illustrates the temperature dependence of resistance. The effect is caused by the fact that the electrons moving through the wire collide with vibrations (phonons) created in the material by thermal noise. At lower temperatures this will happen less, and thus the resistance goes down. In semiconductors and insulators an opposite effect occurs, where resistance decreases with temperature due to the lowering of the Fermi level, and thus less electrons being in the conduction band.
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.
