The quantum hypothesis, first suggested by Max Planck (1858-1947) in 1900, postulates that light energy can only be emitted and absorbed in discrete bundles called quanta. Planck came up with the idea when attempting to explain blackbody radiation, work that provided the foundation for his quantum theory.

Energy can be gained or lost only in integral multiples of a quantum. Figure 1.2.1 1.2. 1: Relationship between the temperature of an object and the spectrum of blackbody radiation it emits. At relatively low temperatures, most radiation is emitted at wavelengths longer than 700 nm, which is in the infrared portion of the spectrum.

21.1 Planck and Quantum Nature of Light
That said, to discover quantum states within a phenomenon that science had always considered continuous would certainly be surprising. When Max Planck was able to use quantization to correctly describe the experimentally known shape of the blackbody spectrum, it was the first indication that energy was quantized on a small scale as well.
Quantum mechanics
quantum mechanics, science dealing with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents— electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons.

Quantum
In physics, a quantum (pl.: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction.Quantum is a discrete quantity of energy proportional in magnitude to the frequency of the radiation it represents. The fundamental notion that a property can be "quantized" is referred to as "the hypothesis of quantization".
Planck's Quantum Theory
Planck's Quantum Theory. According to Planck's quantum theory, Different atoms and molecules can emit or absorb energy in discrete quantities only. The smallest amount of energy that can be emitted or absorbed in the form of electromagnetic radiation is known as quantum.

Max Planck Formulates Quantum Theory
In 1900, 42-year-old Planck discovered an equation that explained the results of these tests: E=Nhf, with E=energy, N=integer, h=constant, f=frequency. In determining this equation, Planck came up with the constant (h), which is now known as " Planck's constant ." The amazing part of Planck's discovery was that energy, which appears to be ...
Quantum Hypothesis
Quantum mechanics began with the solution of the problem of blackbody radiation by Planck's quantum hypothesis: In the interaction of light with matter, energy can only be exchanged between the light in a cavity and the atoms in the walls of the cavity by the discrete amount. (1)

Photoelectric Effect
Photons: The Quanta of Light According to the Planck hypothesis, all electromagnetic radiation is quantized and occurs in finite "bundles" of energy which we call photons. The quantum of energy for a photon is not Planck's constant h itself, but the product of h and the frequency. The quantization implies that a photon of blue light of given frequency or wavelength will always have the same ...
Planck's Quantum Theory: Black Body Radiation, Postulates
Planck's quantum theory has the following presuppositions: Discrete packets or bundles of energy are emitted or absorbed intermittently by matter. Quantum is the name given to the smallest bundle or packet of energy. Using light as an example, a photon is a quantum of light. The absorb quantum energy is proportional to the radiation frequency.

11.2: Planck's Quantum Theory
Initially, his hypothesis explained only one set of experimental data—blackbody radiation. If quantization were observed for a large number of different phenomena, then quantization would become a law. In time, a theory might be developed to explain that law. As things turned out, Planck's hypothesis was the seed from which modern physics grew.
What is Planck's Law
Planck's law is a pioneering result of modern physics and quantum theory. Planck's hypothesis that energy is radiated and absorbed in discrete "quanta" (or energy packets) precisely matched the observed patterns of blackbody radiation and resolved the ultraviolet catastrophe. Using this hypothesis, Planck showed that the spectral ...

This is a superposition of waves. Similarly, in quantum science, objects such as electrons and photons have wavelike properties that can combine and become what is called superposed.

Einstein was able to use Plank's quantizations hypothesis to explain the photoelectric effect, where a "particle of light," a photon, had a characteristic energy described by Plank's constant As can be showed in figure 6.2.2, a minimum energy of 2.0 eV is required to eject a photon off of potassium, and so red light would not work, while green ...
