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.
Simultaneity principle: The principle which all frames of reference will contain invariant simultaneity; that is, the two events perceived as simultaneous (that is, containing the similar time coordinate) in one frame will be apparent as simultaneous
Rayleigh criterion: resolving power: The criterion for determining how delicately a set of optics might be able to differentiate. This starts with the supposition that central ring of one image must fall on the first dark ring of the other; for
Briefly state how does the elevation and air pressure affects the boiling point of water?
Photovoltaics (PV): It transform light directly into electricity. The typical current residential installation of 12m2 could produce around 1,300 kWh pa with a peak of around 1.9kW, though larger and more efficient installations are possibl
Superconductivity: The phenomenon by which, at adequately low temperatures, a conductor can conduct the charge with zero (0) resistance. The current theory for describing superconductivity is the BCS theory.
: A voltage v = 150 + j180 is applied across an impedance and the current flowing is I = 5 - j4 find ? A, impedance . B, resistance. C, reactance. D, power consumed.
Explain Ampere's law? Ampere's law (A.M. Ampere):
Pfund series: The series that explains the emission spectrum of hydrogen whenever the electron is jumping to the fifth orbital. Each line is in the infrared part of the spectrum.
Ohm: Omega: O (after G. Ohm, 1787-1854) The derived SI unit of electric resistance, stated as the resistance among two points on a conductor whenever a constant potential difference of 1 V generates a current of 1 A in the conductor;
