TED-Ed: Light waves, visible and invisible - Lucianne Walkowicz

The video explores how humans perceive only a small part of the light spectrum, known as visible light. It explains light as electromagnetic waves with varying wavelengths and frequencies, affecting how we see colors. The interaction of light with the retina, through rods and cones, enables color perception. Beyond visible light, other forms like radio waves and x-rays exist, detectable by special instruments. The universe emits a full spectrum of light, observable with telescopes, allowing us to study distant celestial bodies.
