EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -Quantum theory states that there are only certain allowed energy states for an electron and that these are quantized. 5. Further, it tells us that no two electrons, in the same system, can occupy the same energy state, and that all the energy states are filled from the lowest levels to the highest levels.

Detailed explanation-3: -Quantum physics is the study of matter and energy at the most fundamental level. It aims to uncover the properties and behaviors of the very building blocks of nature. While many quantum experiments examine very small objects, such as electrons and photons, quantum phenomena are all around us, acting on every scale.

Detailed explanation-4: -The three themes of quantum theory-the quantization of energy and the probabilistic behavior of energy quanta, the wave–particle nature of some matter, and Planck’s constant-formed an interrelated set of ideas that lacked a universality and coherence necessary for them to constitute a scientific theory.

Detailed explanation-5: -The two most recent attempts to construct a quantum theory of gravity are Superstring theory and canonical (Hamiltonian) quantization using so-called Ashtekar variables.
