Chapter 24: Quantum Physics Flashcards
What is quantum physics?
“Quantum physics is the branch of physics that deals with the behavior of matter and energy at very small scales
What is the concept of quantization?
“Quantization refers to the idea that certain properties
What is Planck’s constant?
“Planck’s constant (h) is a fundamental constant that relates the energy of a photon to its frequency: E = hf
What is the photoelectric effect?
“The photoelectric effect is the phenomenon where electrons are ejected from a material when light of a sufficient frequency strikes it
What is the de Broglie hypothesis?
“The de Broglie hypothesis proposes that all particles
What is the wave-particle duality?
“Wave-particle duality is the concept that particles such as electrons and photons exhibit both wave-like and particle-like properties
What is the Heisenberg uncertainty principle?
“The Heisenberg uncertainty principle states that it is impossible to simultaneously measure both the position and momentum of a particle with absolute precision.”
What is the Schrödinger equation?
“The Schrödinger equation is a fundamental equation in quantum mechanics that describes the evolution of a quantum state over time.”
What is a wave function?
“A wave function is a mathematical description of the quantum state of a system. The square of its absolute value represents the probability of finding a particle in a given region.”
What is the concept of superposition?
“Superposition is the principle in quantum mechanics that a system can exist in multiple states at once
What is quantum entanglement?
“Quantum entanglement is a phenomenon where the quantum states of two particles become linked
What is the concept of quantum tunneling?
“Quantum tunneling is the phenomenon where particles can pass through potential barriers that they classically could not overcome
What is the uncertainty in energy and time?
“The uncertainty principle also applies to energy and time
What is the Pauli exclusion principle?
“The Pauli exclusion principle states that no two fermions (such as electrons) can occupy the same quantum state simultaneously.”
What is a quantum harmonic oscillator?
“A quantum harmonic oscillator is a quantum mechanical system that describes a particle subject to a restoring force proportional to its displacement
What is the concept of energy quantization in a quantum harmonic oscillator?
“In a quantum harmonic oscillator
What is the concept of photon energy?
“Photon energy is the energy carried by a photon
What is the concept of wave-particle duality in the context of light?
“Wave-particle duality in the context of light means that light behaves as both a wave (showing interference and diffraction) and as a particle (photons in the photoelectric effect).”
