Wave-Particle Duality - Part 2

Mr. Anderson explains wave-particle duality, focusing on how light, typically seen as a wave, also exhibits particle-like properties, known as photons. He discusses the photoelectric effect, where UV light on metal releases electrons, demonstrating light's particle nature. Einstein's analysis showed energy relates to frequency, not amplitude, proving light's dual nature. The video includes a demonstration of the photoelectric effect, highlighting the immediate release of electrons at the right frequency, reinforcing the concept of light as particles.

What is the term used to describe light when it behaves like a particle?

• Neutron

• Photon

• Electron

• Proton

Which scientist is associated with analyzing the photoelectric effect?

• Albert Einstein

• Niels Bohr

• Isaac Newton

• Marie Curie

What happens when UV light is shone on metal in the context of the photoelectric effect?

• The metal melts

• The metal changes color

• The metal becomes magnetic

• The metal emits electrons

In the photoelectric effect experiment, what change causes electrons to be emitted?

• Changing the light's frequency

• Increasing the light's intensity

• Changing the light's color to red

• Decreasing the light's intensity

What is the main evidence that supports the particle nature of light in the photoelectric effect?

• Electrons are emitted immediately at the right frequency

• Electrons are emitted after a delay

• Electrons are emitted only with increased amplitude

• Electrons are emitted regardless of light frequency
