Apr 25, 2024 · Modern Physics is a branch of physics that deals with the fundamental nature of the universe with post-Newtonian concepts. In the early twentieth century, some experimental results could not be matched with the predictions of classical physics, which describes physical phenomena at an ordinary scale.
There are two main reasons. The first is that knowledge of classical physics is necessary to understand modern physics. The second reason is that classical physics still gives an accurate description of the universe under a wide range of everyday circumstances. Modern physics includes two revolutionary theories: relativity and quantum mechanics.
Modern Physics believes in the dual nature of both particle and wave nature of matter. It provides a microscopic vision of matter, It is based upon Planck’s quantum theory of light and De Broglie’s idea of matter-wave. Atomic Physics, Nuclear Physics, Relativistic Physics, and Quantum Physics are examples of modern Physics.
Modern Physics Problems. Two areas of modern physics are addressed through example problems on this page. Special Relativity problems ask you to relate the observations of two observers measuring the same thing. In Quantum Mechanics problems, you may look at wave or particle behavior of light and subatomic particles.
Albert Einstein is known as the father of modern physics. He was a 20th-century scientist, who came up with the most important ideas. One of the important works of Albert Einstein is the theory of relativity and the famous equation E=mc 2. He was awarded the Nobel Prize for physics in 1921 for his achievements in theoretical physics ...
