Revision Session: Constants and Equations

This lecture covers fundamental constants in physics and chemistry, such as the speed of light, gravitational acceleration, Planck's constant, Avogadro's number, and more. It also delves into key equations related to energy levels in atoms, photon energy, and the structure of matter. The session discusses the significance of quantized energy transfer and the behavior of electromagnetic radiation. Additionally, it explores the principles of diffraction, interference, and the photoelectric effect. The lecture concludes with a focus on atomic structure, including the discovery of neutrons and the concept of isotopes.
