5 Questions
What experimental evidence conclusively established the particle behavior of light?
The photoelectric effect
Which phenomena provide exclusive evidence for the wave behavior of light?
Interference and diffraction
In what way does light exhibit wave-particle duality?
As an advancing wave in some phenomena and as a flux of particles in others
What did de-Broglie's hypothesis propose about the nature of radiation?
Radiation, which is basically a wave, can exhibit particle nature under certain circumstances
What is the key idea behind de-Broglie's hypothesis?
Nature likes symmetry, so if particles can exhibit wave nature, then waves can exhibit particle nature
Study Notes
Experimental Evidence for Particle Behavior of Light
- The conclusive experimental evidence was provided by Albert Einstein's photoelectric effect experiment in 1905, which showed that light can behave as particles (photons) under certain conditions.
Exclusive Evidence for Wave Behavior of Light
- The phenomena that provide exclusive evidence for the wave behavior of light include:
- Interference (e.g., Young's double-slit experiment)
- Diffraction
- Superposition
Light's Wave-Particle Duality
- Light exhibits wave-particle duality, meaning it can exhibit both wave-like and particle-like behavior depending on how it is observed.
de-Broglie's Hypothesis
- In 1924, Louis de Broglie proposed that all radiation, including light, can exhibit wave-like behavior.
- The key idea behind de Broglie's hypothesis is that particles, such as electrons, can exhibit wave-like behavior, and vice versa.
