Brewster’s Law | Statement | Explanation

Brewster’s law is based in the polarization of light by reflection. Polarization is the phenomenon of in which vibrations of light waves are restricted in a plane which is perpendicular to the direction of wave motion. The light in which the vibrations of all electric vectors is in all possible directions perpendicular to the direction […]

Huygens’ Principle

The phenomenon of propagation of light how occurs is explained by Huygens’ principle. The locus of all the points to which all the wave reaches at a time or simultaneously so that all that points are in the same state or phase. Such locus of points is called as wave front. And the normal or […]

Newton’s Law of Cooling Statement Limitations

Statement: According to Newton’s law of cooling, the rate of loss if heat energy Q is directly proportional to the temperature difference between the temperature of the body and the surrounding. Explanation: Let T be the temperature of the body which is greater than the temperature of the surrounding To. Then according to Newton’s law […]

Stefan’s Law of Radiation

The Stefan’s law of radiation is applicable to both ordinary bodies and also to perfectly blackbody. Statement: The Stefan’s law of radiation states that the quantity of radiant energy emitted per unit time per unit surface area is directly proportional to the fourth power of the absolute temperature of the perfectly blackbody. Explanation: If Q […]

Law of Equipartition of Energy

The number of ways by which we can locate a molecule in a system of coordinates are called as degrees of freedom. All we know that, a molecule which is moving along a line requires only one coordinate to locate it. That means it requires only one degree of freedom to locate it. In similar […]

Kirchoff’s Law of Radiation

As we know that, if radiant energy is incident on the surface of any body then the incident radiant energy may be partly absorbed, partly emitted, partly transmitted and partly get reflected.   This ability of the body to absorb, reflect, transmit and emit the incident radiant energy is measured in terms of coefficient of […]
