Explain Malus law
Malus' law (E.L. Malus): The light intensity I of a ray with primary intensity I0 travelling via a polarizer at an angle theta among the polarization of the light ray and the polarization axis of the polarizer is specified by: I = I0 cos2 theta.

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.
What do you mean by the term neutral buoyancy? Briefly illustrate it.
Cherenkov radiation (P.A. Cherenkov): The radiation emitted by a huge particle which is moving faster than light in the medium via which it is travelling. No particle can travel faster than the light in vacuum, however the speed of light in other medi
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.
Woodward-Hoffmann rules: The rules leading the formation of products throughout certain kinds of organic reactions.
Explain Faradays laws of electrolysis or describe Faradays first law and Faradays second law? Faraday's laws of electrolysis (M. Faraday):
Transition temperature: The temperature (that is, dependant on the substance comprised) below that a superconducting material conducts electricity with zero resistance; therefore, the temperature above which a superconductor lose its superconductive p
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.
