Electromagnetic Waves: The Spectrum of Light

The video tutorial explains James Maxwell's theory on the interaction between charged particles and electromagnetic fields. It describes how oscillating charged particles emit electromagnetic radiation, which includes light, X-rays, and radio waves. The tutorial details the components of electromagnetic radiation, highlighting the perpendicular vibration of electric and magnetic fields. A visual representation shows these components vibrating along different axes. The video concludes by comparing electromagnetic waves, which can travel through a vacuum, to sound waves that require a medium like air or water.
