      • Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a medium to pass through, they can travel through a vacuum. Light from the Sun reaches Earth through the vacuum of space.

    The electromagnetic spectrum, with the visible portion highlighted. The bottom graph (Visible spectrum) is wavelength in units of nanometres (nm). Generally, electromagnetic radiation (EMR) is classified by wavelength into radio waves, microwaves, infrared, the visible spectrum that we perceive as light, ultraviolet, X-rays and gamma rays.

    Oct 21, 2024 · In his formulation of electromagnetism, Maxwell described light as a propagating wave of electric and magnetic fields. More generally, he predicted the existence of electromagnetic radiation: coupled electric and magnetic fields traveling as waves at a speed equal to the known speed of light.
