Quantum mechanics is a fundamental theory in physics that describes the behavior of particles at atomic and subatomic scales. It explains phenomena that cannot be accounted for by classical physics.
congrats on reading the definition of Quantum mechanics. now let's actually learn it.
Quantum mechanics introduces the concept of wave-particle duality, where particles like electrons exhibit both wave-like and particle-like properties.
Heisenberg's Uncertainty Principle states that it is impossible to simultaneously know both the exact position and exact momentum of a particle.
The Schrödinger equation is a key mathematical equation in quantum mechanics that describes how the quantum state of a physical system changes over time.
Quantum superposition allows particles to exist in multiple states or positions simultaneously until they are measured or observed.
Entanglement is a phenomenon where particles become interconnected such that the state of one particle instantly influences the state of another, regardless of distance.
Review Questions
What does Heisenberg's Uncertainty Principle state about the measurement of a particle's position and momentum?
Explain the concept of wave-particle duality in quantum mechanics.
What role does the Schrödinger equation play in quantum mechanics?
A principle in quantum mechanics asserting that it is impossible to simultaneously determine with perfect accuracy both the position and momentum of a particle.
