Master the Mysteries of Photons and Wave-Particle Duality

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.
