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.
Negative feedback principle: It is the idea that in a system where there are self-propagating situations, those new situations tend to act against formerly existing situations. Such a principle is in actuality a restatement of the conservation law.
Woodward-Hoffmann rules: The rules leading the formation of products throughout certain kinds of organic reactions.
Faraday constant: F (M. Faraday): The electric charge fetched by one mole of electrons or singly-ionized ions. It is equivalent to the product result of the Avogadro constant and the absolute value of the charge on an electron; this i
Lawson criterion (J.D. Lawson): This is the condition for the discharge of energy from a thermonuclear reactor. This is usually stated as the minimum value for the product of the density of the fuel particles and the energy imprisonme
Calculate the hot and cold temperature after 25 orbits. Assume a 100kg spherical spacecraft made of aluminum. Assume that the spacecraft is in an equatorial orbit. How is calculation 1 different for a spacecraft in a 90 degree (polar) orbit?
