Quantum Mechanics - Photoelectric Effect & Dual nature of Light | EXPLAINED

The Photoelectric Effect sowed one of the earliest seeds for the ideas of Quantum Mechanics, which ultimately got Albert Einstein his Nobel Prize in Physics. 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬ELEVATE𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 Dedicated courses on Physics IITJAM, CSIR-NET, GATE, TIFR, JEST etc are available on Elevate Classes platform Website► https://www.elevateclasses.in/ Android App► https://bit.ly/3zU71ur iOS App► https://apple.co/3ZPRWVJ (use ORG code - AHGXS) 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬MY NOTES - GDRIVE𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 Find the PDF Scanned copy of my NOTES for this lecture here: https://drive.google.com/drive/folders/15XFAGJD3bQyTmuSYWv2eKS_-neqbVxeU?usp=drive_link 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬VIDEO DETAILS𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 The photoelectric effect is the emission of electrons from a material when light falls on its surface. This phenomenon was first observed by Heinrich Hertz in 1887 and explained by Albert Einstein in 1905. Einstein's explanation showed that light could act as both waves and particles, leading to the development of quantum mechanics. The photoelectric effect has become a crucial aspect of modern physics, with applications in solar cells and photoelectric sensors. The effect occurs when photons of light transfer energy to electrons in the material, causing them to be emitted from the surface. The energy of the photons must be greater than the material's threshold frequency for the effect to occur. 00:00 Introduction 01:51 Photoelectric Experiment 07:32 Experimental Observations 18:33 Einstein's Quantum Theory of Light 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬TELEGRAM𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 Join my Telegram Channel ► https://t.me/FortheLoveofPhysicsYT 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬SUPPORT𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 Your Financial support provides me an additional incentive to create high quality lecture videos.
