Colour and Temperature of Stars
This Teaching Astronomy and Space video clip, from the Institute of Physics (IOP), Teachers TV and the Science and Technology Facilities Council (STFC), shows how it is possible to illustrate how the light emitted by a star is related to the star's temperature. Using a filamernt lamp and a variable resistor, the lamp glows first red, then yellow and eventually white as the voltage is increased and the filament temperature rises.
This is a simple yet effective way of demonstrating how analysing the light emitted from a star can give information about its temperature.
