L’emissione di luce della lampadina da bicicletta
A series of three simple experimental activities with bycicle lamps allows a determination of the temperature of the filament, an evaluation of the light emission of the lamp. and an examination of the law for the dependence of the illumination on the distance from the source, with a motivational spur due to the use of both poor material and modern instrumentation for computer aided acquisition of data.
