What is modern physics?
Modern physics is the branch of physics that deals with the study of the fundamental nature of matter and energy at the atomic, nuclear, and subatomic levels. It encompasses a wide range of topics, including quantum mechanics, relativity, particle physics, and cosmology.
Define Cosmology
Cosmology is the study of the origin, evolution, and structure of the universe as a whole. It involves the study of the large-scale structure of the universe, the cosmic microwave background radiation, and the formation and evolution of galaxies.
What does wave-particle duality mean in quantum mechanics?
Particles are always waves
Waves are always particles
Particles can exhibit wave-like behaviour and vice versa
Particles and waves are completely separate entities
What was the first experiment to demonstrate the wave-particle duality of light?
Double-slit experiment
Photoelectric effect
Blackbody radiation
Compton scattering
What is the uncertainty principle?
The principle that the position and momentum of a particle cannot be known simultaneously
The principle that the energy and momentum of a particle cannot be known simultaneously
The principle that the position and energy of a particle cannot be known simultaneously
The principle that the charge and spin of a particle cannot be known simultaneously
