Planck radiation law
A law that defined blackbody radiation better than its predecessor, therefore resolving the ultraviolet catastrophe. It is depend on the supposition that electromagnetic radiation is quantized.
At thermodynamic temperature T, for a blackbody, the radiancy R onto a range of frequencies among nu & nu + dnu is provided by
R = 2 pi h nu3/[c3 [exp (h nu/k T) - 1]].
what is acqustic phenomenon?
Polarization: The dipole moment per unit volume of the solid is the sum of all the individual dipole moments within that volume and is called as 'Polarization' P of the solid.
How to obtain localized fringes
There are imaginary lines or path of the field in the given direction. The lines of force are assumed to make a closed path beginning from N pole and ending at S pole with no loss.
What are Newton s laws of motion? 1. A body at rest will stay at rest and one in motion will stay in motion, unless and unless acted upon by an external force. (Law of inertia)
Q) why we cant use the nuclear reactor concept in making fuel for our usages? Ans) Beacause nuclear reacters produse a huge energy which can''t be in our control and we can''t co
Define the Magnets Magnets work according to rules similar to electric charges. All magnets have two poles, north (actually north-seeking) and south poles. Like poles repel and
The operation of a logic gate or circuit can be shown in a table which have all possible inputs and their corresponding output is known as the truth table. To write the truth table
Explain the Electric Forces and Fields This can be thought of in terms of an electric field, E, similar to the gravitational field discussed earlier [Fg = m g( r ) where at the
