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.
