Hi there!
Quantum mechanics is the 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.
These properties include the interactions of the particles with one another and with electromagnetic radiation (Eg. Light, X-rays, and Gamma rays).
It is important to realize that quantum mechanics is a branch of physics and that the business of physics is to describe and account for the way the world—on both the large and the small scale—actually is and not how one imagines it or would like it to be.
The study of quantum mechanics is rewarding for several reasons.
♦ First, it illustrates the essential methodology of physics.
♦ Second, it has been enormously successful in giving correct results in practically every situation to which it has been applied.
There is, however, an intriguing paradox. In spite of the overwhelming practical success of quantum mechanics, the foundations of the subject contain unresolved problems—in particular, problems concerning the nature of measurement.
An essential feature of quantum mechanics is that it is generally impossible, even in principle, to measure a system without disturbing it; the detailed nature of this disturbance and the exact point at which it occurs are obscure and controversial.
Thus, quantum mechanics attracted some of the ablest scientists of the 20th century, and they erected what is perhaps the finest intellectual edifice of the period.
Thank you! for asking the Question.. :)
Cheers!

Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science
