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?s interactions with matter have also helped shape the structure of the universe.

The most prominent advocate of a particle theory of light was Isaac Newton. Newton?s careful investigations into the properties of light in the 1660s led to his discovery that white light consists of a mixture of colours.

Light - Reflection, Refraction, Physics: Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing.

light, That portion of the electromagnetic spectrum visible to the human eye. It ranges from the red end to the violet end of the spectrum, with wavelengths from 700 to 400 nanometres and frequencies from 4.3 � 10 14 to 7.5 � 10 14 Hz.
Light - Wavelength, Frequency, Amplitude | Britannica

Light - Wavelength, Frequency, Amplitude: From ripples on a pond to deep ocean swells, sound waves, and light, all waves share some basic characteristics. Broadly speaking, a wave is a disturbance that propagates through space.

The spectrum of visible light includes photons with energies ranging from about 1.8 eV (red light) to about 3.1 eV (violet light). Human vision cannot detect individual photons, although, at the peak of its spectral response (about 510 nm, in the green), the dark-adapted eye comes close.
Optics | History, Applications, & Facts | Britannica
3 Mar 2025 at 12:19am
Optics, science concerned with the genesis and propagation of light and with the changes that it undergoes and produces. Physical optics deals with the nature of light itself. Geometrical optics has to do with the principles that govern the image-forming properties of devices that make use of light.
