explain the idea of blackbody radiation, include a discussion of the following topics:
• Why is Planck’s law of radiation important in the history of physics? What are Wien’s law and the Stefan-Boltzmann law, and how are they related to Planck’s law?
• How are these laws applied in astrophysics and other areas of science? Give some examples.

Solutions

Expert Solution

In 1965, the cosmic microwave background radiation (CMBR) was discovered by Penzias and Wilson, who later won the Nobel Prize for their work. The radiation spectrum was measured by the COBE satellite and found to be a remarkable fit to a blackbody curve.

In an experiment to measure the photon statistics of thermal light, the radiation from a blackbody source is filtered with an interference filter of bandwidth 0.1 nm centered on 500 nm, and allowed to fall on a photon-counting detector. Calculate the number of modes incident on the detector, and hence discuss the type of statistics that would be expected.
