Unlocking the Secrets of Light and Electrons: A Journey into the World of Physics

Science Earth Sciences

Explore the fascinating world of light and electrons with this comprehensive article. From the dual nature of light to the subatomic particles that make up our universe, delve into the depths of physics and expand your knowledge.

Understanding Electrons

⚛️Electron is a subatomic particle with negative charge and mass much less than protons.

🔬Joseph John Thompson identified electron as a particle in 1897 using cathode ray tubes.

🌌Similar to light, the nature of electrons has been a topic of discussion in the scientific community.

Exploring the Dual Nature of Light

🌈Light can behave as both particles and waves, proven through experiments and theories.

💡Max Planck proposed light quantum as finite energy pockets, while Albert Einstein introduced photon theory.

🔍Scientific community accepted the dual nature of light based on various observations and discoveries.

Phenomena of Light

🌈Dispersion is the separation of white light into several colors or wavelengths.

🌈Rainbows display the dispersion of light through water droplets acting as prisms.

💨Scattering of light occurs when light rays deviate from their path upon striking obstacles like dust or gas.

Wave-Particle Duality

⚛️🌈Electrons and light exhibit wave-particle duality.

🌌Light phenomena include dispersion, scattering, interference, and diffraction.
