physics branches are
1.OPTICS: this is the physics branches that is concern with the study of light. Under optics physics we talk about electromagnetic radiation (EMR) like ultraviolet light and son.
Optics has three branches, they are:
Geometrics optics– which deal with the study of light as rays
Physical Optics-which is the study of light as waves
Quantum optic: it is the study of light as particles.
2.Modern Physics: This branch of physics which focuses on the theory of relativity and quantum mechanics. Quantum mechanics deal with the behavior of smallest particles while the theory of relativity deals with the relationship between electromagnetism and mechanics. The founder of the theory of relativity is Albert Einstein while quantum mechanics was discovered by Max Plank.
3.Classical Mechanics: Classical mechanics deal with energy, force, gravitation and may more. This branch of physics can also be called Newtonian mechanics as it was named after Sir Isaac Newton and his law of motions, Classical mechanics studies the motion of macroscopic object as well as cosmic entities like star, galaxies, planet, and the behavior of liquid, solid, gas and many more.
4.Nuclear Physics: The branch of physics is concern with the study of Proton and Neutron, it make up and interaction at the center of atom. The nuclear physics can also be considered as atomic physics. Nuclear physics is in charge of atomic weapon, atomic power and nuclear medicine ion implantation in material engineering designing.
Electromagnetism: It is the study of electromagnetic force, such as light, electric field, and magnetic field. Note that the two form of this branch of physics are electricity and magnetism. Electromagnetism is considered one of the most powerful physics as it is encountered in day to day activities, for example lightening in the sky during a thunderstorm is an electrostatic discharge.
5.Astrophysics: It is one of the physics branches that study object like star, galaxies, planets, comet and other celestial bodies. The astrophysics cannot work alone but apply other branches of physics like electromagnetism, thermodynamics, nuclear physics, quantum mechanics and relativity. Astrophysics focuses on law and theories, interpretation and as well astronomical observation.
6.Thermodynamic: This is one of the physics branches that studies physical quantities like temperature, energy and entropy. Note that the law of thermodynamic controls the interactions of almost everything in this universe today.
The other physics branches are as follow:
- Medical physics
- Solid State physics
- Mathematical/ Theoretical physics
- Particle Physic
- Molecular Physics and many more.
