Frequently Asked Questions
What is Modern Physics?
Modern Physics is the branch of Physics that deals with the post Newtonian concepts. It is based on the two major breakthroughs of the twentieth century which are: Relativity and Quantum Mechanics.
Quantum Mechanics involves the distances related to atoms whereas Relativity involves velocities compared to the speed of light.
What are the 5 branches of Modern Physics?
The five branches of Modern Physics are:
Mechanics: Mechanics deals with the motion of an object with or without the application of force.
Optics: This branch deals with the behavior, propagation, and properties of light.
Thermodynamics: This branch deals with the study of heat and its relation with work and energy.
Electromagnetism: It deals with the study of electromagnetic force like electric fields, light and magnetic fields. There are aspects of electromagnetism: Electricity and Magnetism.
Relativity: This branch of Physics deals with the theorem by Albert Einstein which states, space and time are relative and all motion must be relative to a frame of reference.
Acoustic: Acoustic deals with the study of sound and its transmission, production, and effects. It involves mechanical waves in solids, liquids, and gases.
Who is the father of Modern Physics?
Galileo Galilei is considered the father of Modern Physics. He was an Italian physicist, mathematician, and astronomer, his contributions include finding the motion of bodies and the invention of the telescope.
Is Modern Physics Tough in JEE Main?
Modern physics is considered an easier and higher-scoring topic in the JEE Main exam. Modern physics does not contain lengthy calculations, it involves understanding concepts like the photoelectric effect, Bohr’s model, and radioactivity. There are more formula based questions in modern physics which makes it easier for well prepared students.
What are the two main features of modern physics?
The two fundamental features of modern physics are quantum theory and the theory of relativity. The quantum theory explains the behavior of particles at the atomic and subatomic levels. The main principles of quantum theory are the photoelectric effect, wave-particle duality, and Heisenberg’s uncertainty principle. The theory of relativity was proposed by Albert Einstein and it focuses on objects moving at high speeds, and concepts like time dilation and length contraction.
