Energy - Blackbody Radiation Flashcards
Maxwell Equations
Describes behaviour of electric and magnetic fields, and how they relate to one another, describing their manifestations of the same phenomenon
Why did determinisitc physics collapse?
Ultraviolet Catrastrophe and non-existence of luminiferous aether
Ultraviolet Catastrophe
A prediction by classicaly electromagnetism that intensity of black body radiation at thermal equilibrium goes to finifinity as wavelength decreases.
Rayleigh-Jeans Law
Black bodies in thermal equilibrium emit radiaiton at all frequencies, as it increases, so does energy of radiation emission
Luminiferous Aether
This is the volume medium of space light propogates
What are the maxwell equations based on?
Luminferous aether
What is blackbody radiation a function of in classical physics?
Frequency for a fixed temperature(Rayleight jeans law_
What did planck describe light as to resolve UV catastrophe?
Described light as discrete quanta of energy called photons
Newtons Corpuscular Theory of LIght
Said that light was made of particles having neglible mass
Blackbody
A theoretical model absorbing wave lengths of all frequencies, yet only emitting wavelengths characteirsitc of its own temperature
Wiens Displacement Law
Describes how blackbody temperature increase means overall radiated energy increases, meaning peaks of raidation curve become shorter.
Stefan Boltzmann Law
Says flux density emitted by a blackbody, is to the fourth power proportional of its absolute temperature.
