Energy, Particles, and Waves Concepts

This video tutorial covers key concepts in modern physics, including wave-particle duality, mass-energy equivalence, and particle physics. It explains how to perform calculations using E=mc², discusses energy levels and transitions in atoms, and provides practice with free response questions. The tutorial is designed to help students prepare for the Regents exam by reviewing past exam questions and solutions.
