    In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. [4][5] In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum, and polarization.

    Light radiates from a source in waves. Each wave has two parts; an electric part, and a magnetic part. That's why light is called Electromagnetic Radiation.

    May 20, 2023 · Is light a ray or wave? Light is an electromagnetic wave and the straight line paths followed by narrow beams of light, along which light energy travels, are called rays. Light always travels in straight lines although its direction can be changed by reflection or refraction.

    Nov 14, 2024 · In its simplest form, quantum theory describes light as consisting of discrete packets of energy, called photons. However, neither a classical wave model nor a classical particle model correctly describes light; light has a dual nature that is revealed only in quantum mechanics.

    Light is a form of energy produced by a light source. Light is made of photons that travel very fast. Photons of light behave like both waves and particles. Light sources. Something that produces light is called a light source. There are two main kinds of light sources:
