In order to explain black body radiation Max Planck had to introduce the idea that electromagnetic radiation was emitted in discrete packets or "quanta" rather than continuous waves. Each quantum had a fixed energy given by E = hf where h is a constant and f is the frequency.

∙ 13y agoDuring the nineteenth century the main theory in physics was still Newtonian Mechanics. With the advances in electricity, magnetism and the studies about light, it was clear that the theory had its limitations. The limitations appeared in the limits of the too small (atomic size) or the too fast (light speed). The study of the small limit took a long path and it has several contributors. It started in the beginning of the 1900s and laid the foundation of the modern quantum and particle physics.

What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
What is the alternative to quantum mechanics?
Classical Mechanics and Wave Theory.
What is the Alternative to the Quantum Mechanics theory?
There is no reasonable alternative to quantum mechanics, at least not something that can even compare with the predictive power and experimental accuracy as quantum theory. If you want to make predictions about things happening at small scales you cannot do without quantum mechanics. Also note that certain models which are now considered as possible theories of everything (e.g. string theory) all expand upon quantum mechanics, they do not make quantum mechanics invalid or unnecessary.
Quantum Mechanics for Dummies?
This is the title of a book that teaches how to perform the calculations of Quantum Mechanics, in very simple easy to follow terms.
How does light waves and radioactive decay relate to Quantum Mechanics?
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.
When was Principles of Quantum Mechanics created?
Principles of Quantum Mechanics was created in 1930.
Who named the photon?
Max Planck came up with the idea of a photon of energy, suggesting that instead of waves, each photon had a discrete amount, or a quantum hence the foundation of quantum mechanics. I assume it was him who gave it the name.
How did Bohr improve Planck's theoory?
Bohr came up with the planetary model for the hydrogen atom - that began the physical explanation of quantum mechanics invented by Planck.
Why it is said relativistic quantum mechanics?
The distinction is sometimes made to distinguish normal quantum mechanics (which does not incorporate special relativity) and quantum field theory (relativistic quantum mechanics). Since we know special relativity is correct it is the relativistic form of quantum mechanics which is true, but non-relativistic quantum mechanics is still used, because it is a good approximation at low energies and it is much simpler. Physics students typically study regular quantum mechanics before moving on to quantum field theory.
Is newton known for quantum mechanics?
The concepts of quantum mechanics were not explored until the 20th century. Newton only lived into the 18th century, so Newton did no work on quantum mechanics.
What is a mixed state in quantum mechanics?
The mixed state in quantum mechanics is the statistical ensemble of the pure states.
Who created Quantum Mechanics and is it true that it is replacing the old physics?
Quantum Mechanics "replaced" Classical Mechanics in particle physics in mid-1930s.
Quantum mechanics is considered successful because most experiments designed to test quantum mechanics support the theory?
yes. 100%. look up the atomic spectra of helium for a good example.
Why quantum mechanics is someone called wave mechanics?
It is also called wave mechanics because quantum mechanics governed by Schrodinger's wave equation in it's wave-formulation.
What is the alternative to quantum mechanics?
Classical Mechanics and Wave Theory.
Is quantum mechanics a set of fields or is it just a lone branch of mechanics?
Quantum mechanics is a separate branch of physics. It is a general term given to all quantum physics. There are many subbranches, for example Quantum chronodynamics which describes the strong nuclear interaction.
Does quantum and wave mechanics deal with matter?
Yes, as well as other things. Quantum mechanics (also called wave mechanics) is the only approach that can accurately predict the probability of where and in what state matter will end up, given certain initial conditions.
