This document defines and describes several branches of physics including optics, astrophysics, mechanics, electronics, nuclear physics, atmospheric physics, acoustics, and electromagnetism. Optics is the study of light and its properties. Astrophysics applies physics to understand astronomical observations. Mechanics deals with energy, forces, and their effects. Electronics concerns circuits using transistors and microchips and the behavior of electrons. Nuclear physics examines atomic nuclei. Atmospheric physics applies physics to the atmosphere. Acoustics studies sound properties. Electromagnetism involves electric and magnetic field interactions.

1. Explains natural phenomena
in the universe

2. ASTROPHYSICS
ATMOSPHERIC PHYSICS

3. OPTICS
Optics is the
scientific
study of sight
and the
behaviour of
light, or the
properties of
transmission
and
deflection of
other forms
of radiation.

4. ASTROPHYSICS
Astrophysics is
the branch of
astronomy
concerned with
the physical
nature of stars
and other
celestial
bodies, and the
application of
the laws and
theories of
physics to the
interpretation of
astronomical
observations.

5.  Mechanics is the
branch of physical
science that deals with
energy and forces and
their effect on bodies
 The practical
application of
mechanics to the
design, construction, or
operation of machines
or tools

6. Electronics is the
branch of physics
and technology
concerned with
the design of
circuits using
transistors and
microchips, and
with the
behaviour and
movement of
electrons in a
semiconductor,
conductor,
vacuum, or gas.
ELECTR
ONICS

7. Nuclear
physics is the
branch of physics
that deals with the
behavior,
structure, and
component parts
of atomic nuclei

8. Atmospheric
physics is the
study of the
application of
physics to the
atmosphere

9. Acoustics is the branch of
physics concerned with the
properties of sound.

10. Electromagnetism is a field
of physics which deals with
the interaction of electric
and magnetic fields.
