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.

One of the most familiar and important forms of energy is light. Nothing is visible to humans when light is totally absent. But light is even more important for other?
Light - Reflection, Refraction, Diffraction | Britannica
28 Apr 2025 at 8:03am
Light - Reflection, Refraction, Diffraction: The basic element in geometrical optics is the light ray, a hypothetical construct that indicates the direction of the propagation of light at any point in space. The origin of this concept dates back to early speculations regarding the nature of light.

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.

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.

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.
