Understanding Quantum Mechanics

What distinguishes quantum mechanics from classical physics in terms of object behavior?

• Quantum mechanics is a theory that explains gravity.

• Quantum mechanics deals with large objects like cars and planes.

• Quantum mechanics is only concerned with the motion of planets.

• Quantum mechanics describes the behavior of individual atoms and electrons.

What is the concept of wave-particle duality?

• It claims that particles can only exist in one state at a time.

• It describes how light and matter exhibit both wave and particle characteristics.

• It suggests that matter is only a particle.

• It states that light is only a wave.

How did early experiments demonstrate the wavelike nature of light?

• By measuring the speed of light in a vacuum.

• By observing light's ability to bend around corners.

• By using light to power small engines.

• By splitting light through a prism and observing interference patterns.

What was discovered about light through experiments that showed it comes in discrete chunks?

• Light cannot be split into different colors.

• Light travels faster than sound.

• Light is made of particles called photons.

• Light is a continuous wave.

What is the most significant departure of quantum mechanics from classical physics?

• Quantum mechanics only applies to large objects.

• Quantum mechanics does not involve any mathematical calculations.

• Quantum mechanics is based on probabilities.

• Quantum mechanics relies on absolute certainty.
