Light is a radically different technology company. We design beautiful tools that respect and empower our users and our first product is The Light Phone.

Nov 25, 2025 · 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: …

Over the centuries, our view of light has changed dramatically. The first real theories about light came from the ancient Greeks. Many of these theories sought to describe light as a ray -- a straight line …

Light is a type of energy that enables us to see with our eyes. Light travels from a source, like the sun or a light bulb, to our eyes, and to the surroundings. That is the reason we can see objects during …

Dec 28, 2020 · In plain terms, electromagnetic waves are simply known as light, though the term light is sometimes used to specify visible light (that which can be detected by the eye), and other times is …

LIGHT definition: something that makes things visible or affords illumination. See examples of light used in a sentence.

When light hits a transparent object, it passes through it almost completely without making a significant shadow. Light is a form of electromagnetic radiation that shows properties of both waves and particles.

Nov 25, 2025 · Visible light is but one example of a much broader set of phenomena—an electromagnetic spectrum with no theoretical upper or lower limit to frequencies and wavelengths.

But what exactly is light? We catch glimpses of its nature when a sunbeam angles through a dust-filled room, when a rainbow appears after a storm or when a drinking straw in a glass of water looks …
