Science is about studying the natural world in a disciplined way. It allows us to find evidence with the help of experiments and develops new technologies, medicines and much more that make human life significantly simpler. On the other hand, science has basically been divided into 3 types: chemistry, physics, and Biology. Among all, we are going to explore the different branches of Physics. Yes, Physics is the branch of natural science that deals with the study of motion, gravitation, space, energy, time and much more. Honestly, learning Physics is essential as it is used in ordinary day-to-day existence.
Today, this subject has been divided into various branches. Among all, below are the seven different branches of hysics: 1. Optics 2. Modern Physics 3. Classical Mechanics 4. Nuclear Physics 5. Electromagnetism 6. Astrophysics 7. Thermodynamic.
Optics- The branch of physics deals with the behaviours and the properties of light. Optics usually describes the behaviours of electromagnetic radiations (EMR) like ultraviolet- (UV) is electromagnetic radiation with a wavelength from 10 nm to 400 nm, infrared light (IR), is electromagnetic radiation (EMR) with wavelengths extends from 700 nm to 1000000 nm etc. Today, Optics has three major branches. Geometrical optics is physics which deals with the study of light as rays. Physical optics is the study of light as waves, and the last one; Quantum optics, is the study of light as particles.
Modern Physics- Modern physics is a branch of physics that focuses on the theory of relativity and quantum mechanics. The pioneer of this physics is the founder of the theory of relativity - the greatest physicist - Albert Einstein and the founder of quantum theory- Max Planck. Remember, quantum mechanics deals with the behaviour of the tiniest particles, whereas the theory of relativity deals with the relationship between electromagnetism and mechanics.
Classical Mechanics- Classical Mechanics is a branch of physics that deals with energy, force, gravitation, etc. This branch of physics is named after the most influential scientist of all time, Sir Isaac Newton and his laws of motion. Therefore, this branch is known as Newtonian mechanics. Classical Mechanics studies the motion of macroscopic objects and the cosmic entities such as Stars, Galaxies, Planets, and the behaviours of solid, liquid, gas, and many more.
Nuclear Physics- Nuclear physics deals with studying the protons and neutrons (its constituents and interactions) at the centre of an atom. Thus, nuclear physics helps reveal atomic weapons, atomic power, nuclear medicine ION implantation in material engineering designing and a great deal more. However, Atomic Physics, on the other hand, deals with atoms in isolation.
Electromagnetism- Electromagnetism is a study of electromagnetic forces (existence of electricity) like light, electric fields, magnetic fields, etc. The two aspects of this physics are electricity and magnetism. Remember, electricity is the form of energy borne by elementary particles like the electron. Electromagnetism is considered one of the most powerful physics because electromagnetic force is encountered in day to day existence. For example, Lightning in the sky during a thunderstorm is an electrostatic discharge.
Astrophysics- The branch of natural science, Astrophysics deals with studying astronomical objects like Stars, Galaxies, Planets, Comets and other celestial bodies. This physics likewise focuses on the laws and theories, interpretation as well as astronomical observations. Astrophysics apply many other disciplines of physics such as electromagnetism, thermodynamic, relativity, nuclear physics, quantum mechanics and much more.
Thermodynamics- The branch of physics, thermodynamics, deals with studying physical qualities, including temperature, energy, and entropy. Remember, the laws of thermodynamic control interactions of almost everything in this universe today.
Physics Tuition: To learn the various branches of Physics, it is essential to get proper guidance. Although schools provide lessons on the subjects, it is essential to connect with a professional physics tutor to learn in detail about the various branches of physics. Joining Physics tuition is also another way to study the subject better. However, while hiring a tutor or joining a tuition class, parents and students must check the professional's background.
