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.
What is Planck’s quantum theory for class 11?
According to this theory: Energy emitted or absorbed is not continuous, but is in the form of packets called quanta . In terms of light it is called as photon. Each photon carries an energy which is directly proportional to the frequency of wavelength i.e. E depends upon v (nu).
What is the quantum theory in simple terms?
Definition of quantum theory 1 : a theory in physics based on the concept of the subdivision of radiant energy into finite quanta and applied to numerous processes involving transference or transformation of energy in an atomic or molecular scale. 2 : quantum mechanics.
When was Planck quantum theory?
Max Planck was a German theoretical physicist who discovered the quantum of action, now known as Planck's constant, h, in 1900. This work laid the foundation for quantum theory, which won him the Nobel Prize for Physics in 1918.
What is the value of Planck’s quantum?
Planck's constant is often defined, therefore, as the elementary quantum of action. Its value in metre-kilogram-second units is defined as exactly 6.62607015 × 10−34 joule second.

Why do we need quantum theory?
Quantum theory is needed because many phenomena at the microscopic level can not be explained using classical theory, eg: Photoelectric effect, interaction among elementary particles.
How do you explain quantum physics to a child?
Quantum physics is the study of things that are very, very small. This branch of science investigates the behavior of matter and the activities happening inside of atoms in order to make sense of the smallest things in nature.
Who is concerned with Planck’s quantum theory?
The theory was put forward by German physicist Max Planck. It explains the quantum nature of the energy of electromagnetic waves. Planck's quantum theory deals with phenomena such as the photoelectric effect and the nature of radiated emission which were not explained by the laws of classical mechanics.
What was Albert Einstein’s contribution to the atomic theory?
Einstein also in 1905 mathematically proved the existence of atoms, and thus helped revolutionize all the sciences through the use of statistics and probability. Atomic theory says that any liquid is made up of molecules (invisible in 1905). Furthermore, these molecules are always in random, ceaseless motion.
