Study Notes
Wave-Particle Duality of Light
- Light exhibits wave-particle duality, meaning it can behave as both waves and particles.
- The wave-particle nature of light is evident in its ability to exhibit diffraction and interference patterns, as well as displaying particle-like behavior.
Photon Model of Light
- The photon model of light describes light as composed of particles called photons.
- Photons have both wave-like and particle-like properties.
Interaction of Light with Matter
- The interaction of light with matter is called electromagnetic radiation.
Young's Double Slit Experiment
- The diffraction and interference of light in Young's Double Slit experiment demonstrate the wave-like nature of light.
- The experiment shows that light passing through two slits creates an interference pattern on a screen.
Electric Current
- Electric current is the flow of electrons through a conductor.
- The units of measurement for electric current are amperes (A).
- The symbol used to represent current is I.
- The equation that relates charge, current, and time is I = Q / t, where I is current, Q is charge, and t is time.
- When two oppositely charged conductors are connected together, the electrons flow from the negatively charged conductor to the positively charged conductor, resulting in the neutralization of the charges.
