Which physicist proposed the imaginary experiment known as Schrödinger's Cat?

• Albert Einstein

• Niels Bohr

• Erwin Schrödinger

• Werner Heisenberg

What branch of physics focuses on the study of the small particles that make up matter, such as electrons, protons, and neutrons?

• Classical Mechanics

• Thermodynamics

• Quantum Mechanics

• Electromagnetism

In the Schrödinger's Cat thought experiment, what is placed inside the sealed box along with the cat?

• A bowl of food and water

• A radioactive particle, a hammer, and a flask of poison

• A laser pointer and a ball of yarn

• A small mouse and a bell

According to quantum mechanics, what is the state of the cat inside the sealed box before it is observed?

• It is definitely alive.

• It is definitely dead.

• It is both alive and dead simultaneously.

• Its state cannot be determined by quantum mechanics.

When marbles are fired through a double-slit apparatus, what pattern is observed on the screen behind the slits?

• An interference pattern with multiple bright and dark bands.

• Two distinct bands, corresponding to the two slits.

• A single central band.

• A random scattering of marbles across the screen.

When electrons are fired one by one through a double-slit apparatus without observation, what pattern do they form on the screen?

• Two distinct bands, similar to marbles.

• A single bright spot in the center.

• An interference pattern, characteristic of waves.

• No discernible pattern.

The formation of an interference pattern by electrons in the double-slit experiment, even when fired one by one, demonstrates which fundamental concept in quantum mechanics?

• The uncertainty principle

• Wave-particle duality

• Quantum entanglement

• Quantum tunneling

What happens to the pattern formed by electrons in the double-slit experiment when detectors are placed at the slits to observe which slit each electron passes through?

• The interference pattern becomes more pronounced.

• The electrons stop passing through the slits.

• The interference pattern disappears, and two distinct bands are formed, similar to marbles.

• The electrons gain energy and move faster.

The change in electron behavior from an interference pattern to two distinct bands when observed in the double-slit experiment illustrates which key principle of quantum mechanics?

• Quantum superposition

• The observer effect (wave function collapse)

• Pauli Exclusion Principle

• Heisenberg's Momentum Principle

In the Schrödinger's Cat experiment, what happens to the cat's state when the box is opened and observed?

• The cat's state remains a superposition of alive and dead.

• The quantum world collapses, and the cat is observed in either a definitively alive or definitively dead state.

• The cat instantly gains six more lives.

• The cat escapes the box and runs away.
