Electromagnetic Waves EM Spectrum

The video tutorial explores the origin and nature of electromagnetic waves, highlighting Maxwell's theory that oscillating charges generate these waves. It explains the properties of electromagnetic waves, including their ability to travel through a vacuum and their speed, which is the speed of light. The tutorial also discusses the challenges of generating high-frequency waves in a lab and the historical experiments by Hertz and others that demonstrated electromagnetic waves. Additionally, it covers the wave nature, polarization, and practical applications of electromagnetic waves in communication and technology.
