What is Modern Physics?
Modern Physics is an important chapter in Physics that helps us understand atoms, light energy, subatomic particles, space, time, and the universe.
Classical Physics explains many everyday ideas such as motion, force, heat, light, electricity, and magnetism. But some physical ideas, such as the behavior of atoms and particles, need newer explanations.
Modern Physics includes topics such as quantum mechanics, relativity, particle physics, photons, atomic structure, and high-speed motion. This chapter introduces the concepts that explain nature beyond classical physics.
Quantum Mechanics
Learn about matter and energy at atomic and subatomic levels.
Quantum Mechanics explains ideas such as photons, wave-particle duality, energy levels, atoms, and the behavior of electrons.
Relativity
Understand space, time, motion, gravity, and energy at very high speeds and large scales.
Relativity explains ideas such as time dilation, length contraction, mass-energy relation, and the connection between gravity and space-time.
Particle Physics
Study the smallest building blocks of matter and the forces between them.
Particle Physics explains particles such as electrons, protons, neutrons, quarks, photons, and other fundamental particles.
