HSC Physics Blackbody Radiation
/A tutorial sheet of questions on the blackbody radiation follows.
- An iron bar is heated in a flame. Describe the energy released by the bar at a certain temperature.
- Does a heated iron bar produce a continuous, line emission spectrum, absorption spectrum or a combination of these?
- When a hydrogen discharge tube releases light a series of characteristic wavelengths can be observed. Does the gas produce a continuous spectrum as well?
- What is a black body? Is a blackbody a perfect absorber, a perfect emitter of radiation or both?
- What actually is the black body? Is it the high temperature walls of a container, the gas inside the container or a small hole in the wall of the container?
- A blackbody has its kelvin temperature doubled. Is more energy released at each wavelength?
