Verified answer

Answer:

✨ Quantum mechanics is a branch of physics that studies the behavior of matter and energy at a very small scale, such as atoms, subatomic particles, and photons. It describes the fundamental properties of these particles and how they interact with each other, including phenomena such as superposition, entanglement, and tunneling. Quantum mechanics is a complex and abstract field that has many practical applications, including in the development of new technologies such as quantum computers and quantum cryptography.

.✨ One example of quantum mechanics is the double-slit experiment, which demonstrates the wave-particle duality of matter. In this experiment, a beam of particles, such as electrons, is directed at a screen with two slits. When the particles pass through the slits, they create an interference pattern on a detector screen behind the slits, as if they were waves. However, when the particles are observed, such as by placing a detector at one of the slits, they behave like particles and no longer create an interference pattern. This experiment shows that particles can have both wave-like and particle-like properties, depending on how they are measured.

Explanation:

Explanations with example of Quantum Mechanics :

〽️“The main postulate of quantum mechanics establishes that the state of a quantum mechanical system is specified by a function called the wave function. 〽️
〽️The wave function is a function of the coordinates of the particle (the position) and time. 〽️

〽️We often deal with stationary states, i.e. states whose energy does not depend on time. 〽️
〽️For example, at room temperature and in the absence of electromagnetic radiation such as UV light, the energy of the only electron in the hydrogen atom is constant (the energy of the 1s orbital)”.〽️
