This video lecture on Wave Function and its Physical Significance, a core concept of Quantum Mechanics and Engineering Physics, is designed for BTech 1st Year students. In this lecture, we explain what a wave function (ψ) is, why it cannot be directly observed, and how |ψ|² represents probability density of finding a particle in space.

You will understand the mathematical meaning, physical interpretation, properties of wave function, conditions for a valid wave function (finite, single-valued, continuous, normalizable), and how wave functions describe quantum states. The explanation is simple, conceptual, and exam-oriented, making it perfect for scoring full marks in theory questions.

This lecture is especially useful for BTech 1st Year students of RGPV, including all branches such as CSE, IT, Mechanical, Electrical, Civil, and ECE, and is equally relevant for students from other engineering universities following a similar syllabus.

📘 This Engineering Physics Playlist Includes:
