Understanding Uncertainty Principle (using wave packets)

A complete and detailed explanation of the Uncertainty Principle using the Wave packet Approach - the Fourier transform of a wave packet in position and momentum space and correlating their spread/ uncertainties. 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬ELEVATE𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 Elevate Classes - Find LIVE Batches & Recorded Courses for Physics IITJAM, CSIR-NET, GATE, TIFR, JEST etc on our 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/file/d/1uSfw... 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬VIDEO DETAILS𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 The uncertainty principle in the context of quantum mechanics is a fundamental concept that was formulated by Werner Heisenberg. It states that there is a limit to how precisely certain pairs of complementary properties of a quantum system, such as the position and momentum of a particle, can be simultaneously known. In other words, the more accurately you know one of these properties, the less accurately you can know the other. The uncertainty principle is essential when dealing with wavepackets. As you try to make a wavepacket more localized in position (to know the particle's position more precisely), it will spread out in momentum space (due to its Fourier Transforms), leading to greater uncertainty in the particle's momentum. Conversely, if you want to know the momentum of a particle more precisely (by creating a more focused wavepacket in momentum space), its position uncertainty will increase. In summary, the uncertainty principle in quantum mechanics, when considered in the context of Fourier transforms and the wavepacket approach, highlights the inherent trade-off between knowing a particle's position and momentum with high precision. It's a fundamental constraint in the quantum world and has significant implications for the behavior and description of quantum systems. 00:00 Introduction to Wave packet Approach 05:07 Fourier Transforms 12:40 Position & Momentum Space 28:35 Inverse Proportionality between Δx and Δp 35:06 Gaussian Wave packet 43:49 Heisenberg's Uncertainty Relations 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬TELEGRAM𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 Join my Telegram Channel ► https://t.me/FortheLoveofPhysicsYT 𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬SUPPORT𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬𓏬 Your Financial support provides me an additional incentive to create high quality lecture videos.
