The video explores the concept of wave-particle duality, a fundamental idea in quantum physics. It begins with the introduction of the dual nature of particles and waves, followed by the contributions of Einstein and Planck in understanding light's behavior as both a wave and a particle. The development of atomic models by Rutherford and Bohr is discussed, highlighting the challenges and solutions they encountered. De Broglie's hypothesis on electron wave behavior is introduced, leading to experimental evidence supporting wave-particle duality. The video concludes with the significance of this concept in quantum mechanics.

What concept did Albert Einstein apply to light that was originally introduced by Max Planck?

• The concept of light as discrete energy packets

• The principle of uncertainty

• The theory of relativity

• The idea of light as a continuous wave

What was the major flaw in Rutherford's model of the atom?

• It did not include a nucleus

• It ignored the existence of protons

• It proposed electrons were stationary

• It suggested electrons emit light continuously

How did Niels Bohr resolve the issue with Rutherford's atomic model?

• By suggesting electrons do not exist

• By proposing electrons emit light continuously

• By introducing special orbits where electrons do not emit light

• By eliminating the concept of a nucleus

What hypothesis did Louis de Broglie propose about electrons?

• Electrons behave like waves

• Electrons are stationary particles

• Electrons do not exist

• Electrons are only waves

What did Richard Feynman describe as the central mystery of quantum mechanics?

• The uncertainty principle

• The theory of relativity

• Wave-particle duality

• The existence of black holes
