Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1][2] 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 primary tool for perceiving the world and interacting with it for many organisms.
Understanding the Context
Light from the Sun warms the Earth, drives global weather patterns, and initiates the life-sustaining process of photosynthesis; about 10 22 joules of solar radiant energy reach Earth each day. Light: Science and Applications is an open access journal that publishes the highest quality articles in basic and applied optics and photonics. The meaning of LIGHT is something that makes vision possible. How to use light in a sentence.

So let's understand light a little better right now, through James Clerk Maxwell and the electromagnetic spectrum. At its core, light is a form of electromagnetic radiation, which encompasses a broad range of wavelengths and frequencies. The visible light spectrum, which human eyes can detect, ranges from approximately 400 to 700 nanometers (nm) in wavelength. What is Light? Light in Physics 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 daytime with the sunlight, or with a light bulb in the night.
