What Is Light? Wave or Particle? | Richard Feynman

Описание: What exactly is light? Is it a wave, a particle, or something even stranger?
In this video, we explore the true nature of light and why it behaves like both a wave and a particle—a mystery that reshaped modern physics.

You’ll discover:

How light behaves as a wave

How photons act like particles

The famous double-slit experiment

Wave–particle duality explained simply

Why light doesn’t fit into classical physics

Whether you’re new to physics or just curious about how the universe works, this video breaks down complex ideas in a clear and engaging way.
