The Waves, Optics and Quantum Mechanics Virtual Lab is designed to provide an interactive and simulation-based understanding of fundamental concepts in modern physics. It covers classical oscillatory motion including simple harmonic, damped, and forced oscillations to build a strong foundation in wave dynamics. The lab demonstrates the wave nature of light through Young’s double-slit experiment and explores diffraction phenomena such as Fraunhofer diffraction from single slits and circular apertures. It also enables measurement of laser wavelength using diffraction techniques.
Moving beyond classical physics, the lab introduces the quantum nature of light and matter through virtual experiments on the double-slit experiment, potential wells, quantum harmonic oscillators, and quantum tunnelling. Advanced concepts such as the hydrogen atom and the Kronig–Penney model help learners understand atomic structure and the origin of energy bands in solids. Through visualization, parameter variation, and graphical analysis, students gain both conceptual clarity and analytical skills.
This virtual lab is highly beneficial for undergraduate and postgraduate physics and engineering students, enabling self-paced learning and strengthening theoretical concepts through simulation-based experimentation.
