   Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.

   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: Incandescent sources use heat to produce light.

   The light of such objects is incandescent. Other light sources emit light energy but no heat energy. They are known as luminescent, or cold light, sources. Neon and fluorescent lights are luminescent. Measuring Light. The total amount of light given off by a light source is called the luminous flux. It is measured in units called lumens.

   Is light a wave or a ray?

   • By the 17th century enough was known about the behavior of light for two conflicting theories of its structure to emerge. One theory held that a light ray was made up of a stream of tiny particles. The other regarded light as a wave. Both of these views have been incorporated into the modern theory of light.

   What is a light source called?

   • They are known as luminescent, or cold light, sources. Neon and fluorescent lights are luminescent. The total amount of light given off by a light source is called the luminous flux. It is measured in units called lumens. For example, a 100-watt incandescent lightbulb or a 26-watt compact fluorescent bulb emits about 1,600 lumens.

   Is light made of waves or particles?

   • The debate of whether light is made of waves or particles has been going for hundreds of years. Sir Isaac Newton thought that shadows proved that light was made of particles, but there is a lot of evidence that light is made of waves. Rainbows and prisms can split white light up into different colours.
