INTENSITY OF RADIATION

Objective: Verify the inverse square law for the intensity of radiation from a source of light According to the inverse square law, the intensity of radiation from a light source, i.e. the power per unit area, is inversely proportional ... more

Objective: Verify that intensity of radiation is proportional to the fourth power of the temperature, T4 The way that intensity of radiation from a black body depends on temperature is described by the Stefan-Boltzmann law. Similar dependence ... more
