You make it simple! lol

Answer 2

Planck's law, discovered by Max Planck, is the basis of the quantum theory of electromagnetism.

The law states that the energy associated with electromagnetic radiation comes in indivisible packets called quanta, each of which is associated with a single photon. The size (E) of a quantum depends on the frequency (f) of the radiation, according to the formula :E = hf,
where h is Planck's constant.

Using SI units, energy is measured in joules, frequency is measured in hertz, and Planck's constant has the unit joule seconds.

Sorry, as simple as it gets for a complicated subject.

Answer 3

Planck's law: The fundamental law of quantum theory that describes the essential concept of the quanta of electromagnetic energy.

Note 1:
Planck's law states that the quantum of energy, E, associated with an electromagnetic field is given by E = h, where h is Planck's constant and is the frequency of the electromagnetic radiation. Note 2: Planck's constant is usually given in joule•seconds and the frequency in hertz. Thus, the quantum of energy is usually given in joules. Note 3: The product of energy and time is sometimes referred to as the elementary quantum of action. Hence, h is sometimes referred to as the elementary quantum of action.

Answer 6

In physics, Planck's law of black body radiation predicts the spectral intensity of electromagnetic radiation from a black body at temperature T.

Max Planck originally produced this law in 1900 (published in 1901) in an attempt to improve upon an expression proposed by Wilhelm Wien which fit the experimental data at short wavelengths but deviated from it at long wavelengths. He found that the above function, Planck's function, fit the data for all wavelengths remarkably well. In constructing a derivation of this law, he considered the possible ways of distributing electromagnetic energy over the different modes of charged oscillators in matter. Planck's law emerged when he assumed that the energy of these oscillators was limited to a set of discrete, integer multiples of a fundamental unit of energy, E, proportional to the oscillation frequency ν:
E=h.v

Answer 7

E=hf, where E is energy the emitted and h is the planck's constant, f is the frequency of the wave incident. find the planc's constant by googling or perry's handbook.
