What is modern physics?
Modern physics studies physical theories developed in the 20th century and beyond, including quantum mechanics, relativity, atomic physics, nuclear physics, and cosmology.
What topics are covered in an online modern physics course?
Courses commonly cover special and general relativity, quantum phenomena, atoms, nuclei, radioactivity, particles, and applications in astronomy and energy.
Can I learn Einstein’s general relativity online?
Yes. Online general relativity courses explain spacetime, gravity as curvature, black holes, gravitational waves, and cosmological models.
What will I learn in a nuclear physics and radioactivity course?
You can learn about nuclear structure, radioactive decay, half-life, fission, fusion, radiation detection, and nuclear energy applications.
How is modern physics used in solar energy conversion?
Modern physics explains how photons interact with semiconductor materials in solar cells, enabling the conversion of sunlight into electrical energy.
What is the difference between astrophysics and cosmology?
Astrophysics applies physics to stars, planets, galaxies, and other celestial objects, while cosmology studies the origin, evolution, and large-scale structure of the universe.
Why are thermodynamics and statistical physics important in modern physics?
They connect microscopic particle behavior with measurable properties such as temperature, entropy, energy, phase changes, and heat transfer.
