Diffuse reflection is a feature of light reflected from a dull, and a non shiny surface. In this objects illuminated solely by diffusely reflected light exhibit an equivalent light intensity from all sighting directions. That is, in diffuse reflection light incident on the surface is reflected uniformly in all directions and is attenuated through an amount dependent on the physical properties of the surface. As light is reflected uniformly in all directions the perceived illumination of the surface is not dependent on the place of observer. The Diffuse reflection models the light reflecting properties of the matt surfaces that is, surfaces which are grainy or rough which tend to disperse the reflected light in all the directions. This dispersed light is termed as diffuse reflection.
Stefan-Boltzmann law (Stefan, L. Boltzmann): The radiated power P (that is the rate of emission of electromagnetic energy) of a hot body is proportional to the radiating surface area, A, and the 4th power of the thermodynamic temperature, T. The const
Occam's [or Ockham's] razor (William of Occam [or Ockham]; c. 1340): It is the suggestion that the simpler a theory is the better. When two theories forecast the phenomena to the similar accuracy, then the one that is simpler is the better one. Furthe
Mach number (E. Mach): It is the ratio of the speed of an object in a specified medium to the speed of sound in that medium.
Define Hertz or SI unit of frequency: Hertz: Hz (after H. Hertz, 1857-1894): The derived SI unit of frequency, stated as a frequency of 1 cycle per s; it therefore has units of s-1.
Gauss' law (K.F. Gauss): The electric flux via a closed surface is proportional to the arithmetical sum of electric charges contained in that closed surface; in its differential form, div E = rho,
Cosmic censorship conjecture (R. Penrose, 1979): The conjecture, so far wholly undemonstrated in the context of general relativity, that all singularities (that is with the possible exception of the big bang singularity) are attended

Stefan-Boltzmann constant: sigma (Stefan, L. Boltzmann): The constant of proportionality exist in the Stefan-Boltzmann law. It is equivalent to 5.6697 x 10-8 W/m2/K4.
