In this lecture, we derive the mathematical relation between group velocity and phase velocity and explain their physical significance in the context of wave packets and the wave nature of matter. Students will clearly understand why group velocity represents particle velocity and how the relation between group and phase velocity is frequently asked in engineering physics university examinations. This lecture is especially useful for RGPV BTech 1st Year students from all branches including CSE, IT, Mechanical, Electrical, Civil, and ECE, and is also relevant for students of other Indian engineering universities. 📘 This Engineering Physics Playlist Will Include: Planck’s Quantum Hypothesis De Broglie Wavelength & Wave Nature of Particles Wave Function & Physical Significance Schrödinger Time Independent Wave Equation Schrödinger Time Dependent Wave Equation Wave Packet, Phase Velocity & Group Velocity Relation Between Group Velocity and Phase Velocity Particle in One Dimensional Box Wave Optics: Interference & Diffraction Lasers & Optical Fiber Communication Semiconductors & Solid State Physics Electromagnetic Theory This Video Is Helpful For: BTech 1st Year (RGPV) – All Branches: CSE / IT / Mechanical / Civil / Electrical / ECE Engineering Physics Quantum Mechanics concepts for engineering students Engineering Physics complete syllabus for 1st year university exams Engineering Physics foundation for NET, GATE, IIT-JAM aspirants This concept is very important in Engineering and Applied Sciences. The lecture is also useful for B.Sc., M.Sc., B.Tech, and M.Tech students, and for those preparing for engineering entrance exams and higher studies. 🏷️ Keywords : group velocity phase velocity relation between group velocity and phase velocity engineering physics engineering physics btech engineering physics btech 1st year engineering physics 1st semester engineering physics quantum mechanics quantum mechanics engineering physics quantum physics btech quantum physics engineering 1st year group velocity derivation phase velocity derivation engineering physics unit 1 wave mechanics engineering physics quantum mechanics for engineers engineering physics revision btech 1st year physics engineering physics important questions engineering physics exam preparation rgpv engineering physics education point online sachin sir engineering physics sachin bhardwaaj engineering physics 🔖 Hashtags #EngineeringPhysics #QuantumMechanics #GroupVelocity #PhaseVelocity #RGPV #sachinbhardwaaj
