Summarizing Photon Energies and the Electromagnetic Spectrum

Physics is a science discipline concerned with the nature and properties of matter and energy. Physics topics include mechanics, heat, light and radiation, sound, electricity, magnetism, the structure of atoms, and so on.

Physics

Discover the principles of quantum physics, including Planck&#8217;s contribution, atomic spectra, the photoelectric effect, and the particle-wave duality, and learn about measuring photon momentum, probability distribution, and Heisenberg uncertainty in this tutorial.
