What was the primary point of contention between Albert Einstein and Niels Bohr regarding quantum mechanics?

The randomness of quantum mechanics

The existence of subatomic particles

What phenomenon was Max Planck initially trying to explain?

The nature of classical physics

What was Max Planck's radical proposal in 1900 regarding energy?

Energy comes in discrete small packets called quanta.

Energy can be converted into mass.

At the turn of the 20th century, what experimental observation contradicted existing theories about light?

The spectrum of light emitted by a heated object required an infinite amount of energy according to existing theories.

Light could not be produced from heat.

The speed of light was not constant.

Light was found to be composed of particles, not waves.

What was Planck's groundbreaking idea that helped explain the behavior of light and laid the foundation for quantum mechanics?

Energy is released in discrete, indivisible packets called quanta.

Light's speed is relative to the observer.

Light is made of tiny particles called atoms.
