In the universe energy, matter and go as per quantum. Energy is released in quantum of photon. Electron has a quantum mass. Proton has quantum mass. Both has a quantum charge. Neutron has a quantum mass. Speed of light is a quantum. Big bang is a quantum event essentially occurring at particular mass. It takes a quantum energy for shifting of electrons from one shell to other. In photo-luminescence light energy is released in quantum.
Because light waves and radioactive decay are some of the key factors that lead to the development of Quantum Mechanics. Quantum mechanics is also our best apparatus for describing and predicting those phenomena.
The history of quantum mechanics began with the 1838 discovery of cathode rays by Michael Faraday, the 1859 statement of the black body radiation problem by Gustav Kirchhoff, the 1877 suggestion by Ludwig Boltzmann that the energy states of a physical system could be discrete, and the 1900 quantum hypothesis by Max Planck. Planck's hypothesis stated that any energy is radiated and absorbed in quantities divisible by discrete "energy elements", such that each energy element E is proportional to its frequency ν. Planck insisted that this was simply an aspect of the processes of absorption and emission of radiation and had nothing to do with the physical reality of the radiation itself. However, at that time, this appeared not to explain the photoelectric effect (1839), i.e. that shining light on certain materials can eject electrons from the material. In 1905, basing his work on Planck's quantum hypothesis, Albert Einstein postulated that light itself consists of individual quanta.

That light comes in indivisible chunks (he called them "quanta" but the present term is "photons") and that the energy of each such quanta is equal to the frequency of that light times a constant (now called Planck's Constant). When Max Planck first proposed this idea in 1900, he only noted it as a mathematical curiosity that would permit a solution to the spectrum of black-body radiation. In other words, he didn't assert that it was actual description of reality. In 1905, Einstein noted that this same assumption would fully explain the photoelectric effect.
It means saying what you think is going to happen. For example, if the experiment was 'to test whether plants need light to live', a correct hypothesis would be 'I think the plant will die without light'.

Violet light has greater energy because it has higher frequency than yellow light
A quantum of light is named as " PHOTON" . It is a basic packet or a bundle from which a beam of light is made of!
