What are the branches of modern physics?

Answer 1

The Branches of modern physics are mainly 2.

1)Quantam Physics

2)Relativity

There is also classical physics. as a bonus the branches of classical physics is mainly.

1) Mechanics

2) Electromagnetism

3) Thermodynamics.

P.S. In both modern and classical physics there are more than those branches given but these are like the main ones.
There are seven branches of modern physics. These branches are quantum physics, relativistic physics, low-temperature physics, condensed matter physics, atomic and nuclear physics, solid-state physics, and plasma physics.

Answer 2

Classical: Optics, Mechanics, Wave Physics, Electrodynamics/Magnetism, Thermal, Electricity.

Special and General Relativity can fall into both depending on the depth you go into... this can be said for many of the different branches though

However many of these have cross-overs, i.e. Quantum Electrodynamics - See work by Feynman, Quantum Optics etc

Modern Physics is more hazy... Particle, nuclear, atomic, Quantum.

The definition of modern physics could be generalized to anything that involves the quantization of energy (lumps of energy, rather than continuous). Many problems in modern physics are more accurate (not perfect) descriptions of classical things. For example, Newtons laws of motion work in everyday use, but when you get to about 5% of the speed of light the relativistic effects come into play. So although the Newtonian stuff is an approximation it works very well as long as the velocity is much less than c.

Good examples of the segregation of modern and classical physics are things like the photoelectric effect (Einstein's nobel prize winning work) which shows how light must be a particle.

Also, Young's' Double Slit experiment shows how light is a wave..

Hence, Wave-Particle Duality purposed in De Broglies (ridiculously short PhD thesis. )

Answer 3

The main branches of physics are:

1. Mechanics : It deals with the motion of objects (point or objects with small masses)

2. Optics : It deals with the formation of images using mirrors and lenses

3. Electrodynamics and Magnetism : It deals with the study of charged particles and their magnetic behavior

4. Modern and Nuclear Physics(Quantum Physics) : It deals with atomic collisions and nuclear fission/fusion and photoelectric effect.

5. Thermodynamics : It deals with heat transfer and engines.

Answer 4

The branches of modern physics include quantum mechanics, relativity (both general and special), particle physics, astrophysics, condensed matter physics, and nuclear physics. Each branch focuses on specific phenomena and theories to understand the fundamental nature of the universe.
