Mention two type of physics

Two main branches of physics are:

1. Classical Physics: This branch deals with phenomena that are macroscopic and occur at speeds much slower than the speed of light. It includes areas like mechanics (study of motion and forces), thermodynamics (study of heat and energy), electromagnetism (study of electric and magnetic phenomena), and optics (study of light).

2. Modern Physics: This branch emerged in the early 20th century and deals with phenomena at the atomic and subatomic levels, or at very high speeds. Key areas include quantum mechanics (study of energy and matter at the atomic and subatomic level) and relativity (study of space, time, gravity, and the universe at large scales and high speeds).
