A black body box is an idealized black body radiator. That is, any light emerging from the interior of the box is purely a product of the box’s temperature.
How it works:
As the light emerging from the cavity should be a product of the...
The thermal radiation emitted from a black body is temperature dependant. The tungsten filament of a bulb approximates a black body, and by increasing the current through the bulb, its temperature rises and so its color spectrum shifts to...
10 cm microwaves are used for the demonstration of travelling and standing waves, reflection, interference, refraction, diffraction, absorption, polarization, tunneling, and waveguides.
What it shows:
The following is a sequence of experiments that can...
In explaining the electron orbits in the Bohr atom, de Broglie's principle of particle wave duality allows you to treat the electrons as waves of wavelength nλ = 2πr where r is the radius of the orbit. Then the only orbits allowed are those...
A large square metal plate, supported and harmonically driven at its center, is made to vibrate in any one of its numerous normal modes of vibration. As with the regular Chladni Plates, the two-dimensional standing wave patterns are made...
