Wave Theory and Nature of Light

The video explores the unification of electricity and magnetism by Maxwell, the nature of light as both a particle and a wave, and the limitations of human experience in understanding the universe. It delves into historical debates on light's nature, highlighting Young's double slit experiment that demonstrated light's wave properties. The video also discusses Hertz's experiment, which revealed complexities in light's behavior, challenging the wave theory.

What did Maxwell achieve in the field of electromagnetism?

• He unified electricity and magnetism.

• He developed the theory of relativity.
