The particle theory of light led Pierre-Simon Laplace to argue that a body could be so massive that light could not escape from it. In other words, it would become what is now called a black hole . Laplace withdrew his suggestion later, after a wave theory of light became firmly established as the model for light (as has been explained, neither ...
This theory came to dominate the conceptions of light in the eighteenth century, displacing the previously prominent vibration theories, where light was viewed as "pressure" of the medium between the source and the receiver, first championed by René Descartes, and later in a more refined form by Christiaan Huygens. [1]
The simplest form of a tired light theory assumes an exponential decrease in photon energy with distance traveled: = where () is the energy of the photon at distance from the source of light, is the energy of the photon at the source of light, and is a large constant characterizing the "resistance of the space".
But the particle theory of light can not satisfactorily explain refraction and diffraction. [5] To explain refraction, Newton's Third Book of Opticks (1st ed. 1704, 4th ed. 1730) postulated an "aethereal medium" transmitting vibrations faster than light, by which light, when overtaken, is put into "Fits of easy Reflexion and easy Transmission ...
its predecessors like the theories of luminiferous aether, its early competitors, i.e.: Ritz’s ballistic theory of light, the models of electromagnetic mass created by Abraham (1902), Lorentz (1904), Bucherer (1904) and Langevin (1904). This list also mentions the origins of standard notation (like c) and terminology (like theory of relavity).
Accepted classical theories of physics, and in particular general relativity, predict a constant speed of light in any local frame of reference and in some situations these predict apparent variations of the speed of light depending on frame of reference, but this article does not refer to this as a variable speed of light. Various alternative ...
The theory postulates that light has always the same velocity in respect to the source. [A 28] However de Sitter noted that emitter theory predicted several optical effects that were not seen in observations of binary stars in which the light from the two stars could be measured in a spectrometer. If emission theory were correct, the light from ...
In the 19th century, luminiferous aether (or ether), meaning light-bearing aether, was a theorized medium for the propagation of light. James Clerk Maxwell developed a model to explain electric and magnetic phenomena using the aether, a model that led to what are now called Maxwell's equations and the understanding that light is an ...
