Hereโ€™s What Research Shows Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye.

Understanding the Context

[1][2] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400โ€“700 nanometres (nm), corresponding to frequencies of 750โ€“420 terahertz. Light is a primary tool for perceiving the world and interacting with it for many organisms. 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.

Synonym Discussion of Light. And our entire understanding of the interaction of light and matter requires light to act like particles known as photons.

Final Thoughts

Perhaps the easiest way to think of light is as a stream of particles, but quantum particles, which are unlike ones that we can see. And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think scientists know all the answers, but light continues to surprise them.
