What is quantum physics?

Quantum physics is the branch of physics that deals with the behavior of matter and energy on the atomic and subatomic scales.

Who is considered the father of quantum physics?

Max Planck is often considered the father of quantum physics due to his work on black body radiation and the introduction of the quantum concept.

What is the principle of wave-particle duality?

The principle of wave-particle duality posits that every particle or quantum entity exhibits both wave and particle characteristics.

What is Schrödinger's cat thought experiment?

Schrödinger's cat is a thought experiment that illustrates the principle of superposition in quantum mechanics, where a cat is simultaneously both alive and dead.

What does the Heisenberg Uncertainty Principle state?

The Heisenberg Uncertainty Principle states that it is impossible to simultaneously know the exact position and momentum of a particle.

What is quantum entanglement?

Quantum entanglement is a phenomenon where quantum particles become interconnected and the state of one instantly influences the state of the other, regardless of distance.

Who formulated the principle of complementarity?

Niels Bohr formulated the principle of complementarity, which describes how objects can have mutually exclusive properties that reveal themselves in different experimental setups.

What role does the double-slit experiment play in quantum physics?

The double-slit experiment demonstrates the wave-particle duality of light and matter, playing a crucial role in understanding quantum mechanics.

How does quantum superposition work?

Quantum superposition refers to the quantum system's ability to exist in multiple states simultaneously until measured or observed.

What is Planck's constant?

Planck's constant, denoted as h, is a fundamental physical constant that relates the energy of a photon to its frequency.

What is wavefunction collapse?

Wavefunction collapse is the process by which a quantum system transitions from a superposition of states to a single eigenstate due to measurement.

Who is responsible for the Copenhagen interpretation?

The Copenhagen interpretation was primarily developed by Niels Bohr and Werner Heisenberg.

What is the significance of the quantum tunneling effect?

Quantum tunneling is a phenomenon where particles pass through potential barriers they wouldn't classically be able to surmount.

What challenges did classical physics face that led to the development of quantum physics?

Classical physics couldn't explain phenomena like black body radiation, the photoelectric effect, and atomic spectra, leading to the development of quantum physics.

Why is the Bohr model of the atom significant in quantum physics?

The Bohr model is significant because it incorporated quantum ideas to describe electron orbits in atoms quantized by angular momentum.
