![]() ![]() These types of laws are helpful for practical purposes. We can find many laws in physics like the law of nature, electromagnetic induction, Faraday’s law, etc. It is interesting to learn new concepts or things every day with the help of physics. Physics is an exciting subject that shows us the interesting facts or reasons for the day-to-day happenings in our life. It deals with the things which are neither small nor big. The mesoscopic phenomena are the phenomena that come in between the microscopic and macroscopic phenomena. Optics deals with light concepts like refraction and reflection, image formation, and analysis. Electrodynamics deals with the charge interactions in electric and magnetic fields. In thermodynamics, we can study the relationship between heat and energy and its conversion. In mechanics, we can study the concepts of motion, position, and energy of particles or objects. ![]() The macroscopic phenomena deal with classical physics, which covers the concepts of mechanics and thermodynamics, optics, and electrodynamics. It also helps in studying the law of nature and natural phenomena, including thermal expansions, particle interaction, and gravitational force. All the celestial bodies like the moon, stars, and planets come under the astronomical level. For example, all the things we can see with our naked eyes, like trees, humans, animals, and birds, come under the terrestrial level. It covers both terrestrial and astronomical entities. The macroscopic concept deals with the big things. The theory of relativity elaborates the inertial and noninertial concepts of subatomic particles. Quantum mechanics discusses the universe at the atomic level and covers the concept of the uncertainty principle and charge quantisation, and wave-particle duality. Microscopic phenomena are the foundation of modern physics, which covers the concept of relativity theory and quantum mechanics. The microscopic phenomena can be studied at three levels – nuclear, atomic, and molecular. Each atom consists of one nucleus, which helps us understand the microscopic phenomena of electrons, protons, and neutrons. We cannot see the atoms with our naked eye as the atoms are tiny and micro in size. Those atoms are combined to form the molecules. We know that all things are made up of atoms. The scope of physics has three phenomena – mesoscopic phenomena, macroscopic phenomena, and microscopic phenomena. ![]() The scope of Physics is an important concept that helps in dealing with qualitative and quantitative studies. Therefore, with practical advancements over the years, society has improved a lot more than in the past. Similarly, when Newton gave his three laws, not only did it introduce a new branch of Physics- Newtonian kinematics, but it also improved societal thinking and perception. His invention gave physics a new dimension and improved communication in human society. For example, Alexander Graham Bell, a Scottish engineer, and scientist invented the first telephone with practical function. Physics and society accelerated further as new technologies were invented or facts were discovered. Physics, technology, and society have always been intertwined. ![]()
