Exploring Electromagnetic Radiation and the Spectrum

This video tutorial by Mr. Millings covers electromagnetic radiation, explaining its nature as energy made of photons traveling in waves. It discusses the photoelectric effect, demonstrating light's particle nature, and how prisms show light as waves. The electromagnetic spectrum is detailed, from radio waves to gamma rays, with a focus on the visible light spectrum. The tutorial also teaches how to calculate wave properties like speed, wavelength, and frequency, and how to determine photon energy using Planck's constant.
