Quantum physics is a branch of physics that deals with the behavior of matter and energy at the
atomic and subatomic level. It is a fundamental theory that has revolutionized our understanding
of the nature of the universe and has had a profound impact on many areas of science and
technology.
One of the key principles of quantum physics is the concept of wave-particle duality, which states
that particles, such as electrons and photons, can exhibit both wave-like and particle-like
properties depending on how they are observed. This is in contrast to classical physics, which
om
describes particles as having definite positions and velocities at all times.
The wave-like properties of particles can be observed through phenomena such as diffraction
l.c
and interference. Diffraction refers to the bending of waves around obstacles or through narrow
ai
slits, and it can be observed with light waves as well as particles such as electrons. Interference
gm
refers to the superposition of two or more waves, resulting in a pattern of bright and dark
regions. These phenomena can be observed when light waves pass through a single slit or when
electrons pass through a double-slit experiment.

photoelectric effect and the emission of electrons from a heated cathode. The photoelectric
effect refers to the emission of electrons from a metal surface when it is exposed to light, and it

particles and the work function of the metal.

The wave-particle duality of particles can be described using the Schrödinger equation, which is

time. The wave function, also known as the quantum state, describes the probability of finding a
particle in a particular location. The wave function can be used to calculate the probability of
finding a particle in a particular energy state or the probability of observing a particular outcome
in an experiment.
Another important principle of quantum physics is the uncertainty principle, which states that it
is impossible to simultaneously know the exact position and momentum of a particle with
