Study Notes
Light: Wave-Particle Duality
- The primary characteristic of light is its dual nature: it exhibits properties of both waves and particles. This is known as wave-particle duality.
- Light can be produced through various processes:
- Incandescence: Heating a substance to high temperatures causing it to emit light.
- Fluorescence: Certain materials absorb high-energy radiation (like ultraviolet light) then emit light at lower energy levels.
- Phosphorescence: Similar to fluorescence but the emission of light persists after the excitation source is removed.
- Chemiluminescence: Light produced through a chemical reaction.
- Bioluminescence: Light production by living organisms, often through chemical reactions within their bodies.
- Quantum mechanics provides the explanation for light's wave-particle duality. Light particles are called photons, and they exhibit wave-like behavior when traveling through space.
- Refraction, the bending of light as it passes from one medium to another, causes a rainbow. Light is dispersed into its constituent colors due to each color's unique refractive index.
