Describe the limitations of light wave theory in accurately predicting blackbody radiation and Planck's solution

Solutions

Expert Solution

In 1678, Huygen’s proposed that every point that a luminous disturbance meets turns into a source of the spherical wave itself. The sum of the secondary waves, which are the result of the disturbance, determines what form the new wave will take. This theory of light is known as the ‘Huygens’ Principle’.

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.

) Kragh states that quantum theory “owes is origin” to the problem of blackbody radiation. What was this problem? What were some other problems plaguing classical physics at the end of the 19th Century? (b) Briefly explain the history of attempts to solve the blackbody problem: Wien’s 1894 proof, Wien’s 1896 law, Planck’s 1899 derivation of Wien’s law, and Planck’s own radiation law (along with the “quantum hypothesis” made in Dec. of 1900). (c) How well these laws fit the...
