Wave Nature of Light: What is Light?

The video tutorial explores the development of electromagnetic theory, starting with James Clerk Maxwell's equations linking electric and magnetic fields. It explains how electromagnetic waves are generated and their relation to light. The electromagnetic spectrum is detailed, highlighting the range from gamma rays to radio waves, with visible light as a small part. The video also discusses sources of electromagnetic energy, including the sun and artificial sources like fire and electric lights.
