Visible light

Refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, the electromagnetic waves constituting light are refracted when crossing the boundary from one transparent medium to another because of their change in speed.

Researchers have created the first "metalens" that can focus the entire visible spectrum of light onto a single point in high resolution. The breakthrough

In this post, we explore connections between the spectrum of visible light and the use of colours from the light spectrum to represent chakras, theorized to be the energy centres of our electromagn…

Spectroscopes are used to split light into different wavelengths to determine the chemical composition of objects such as stars and elements.

The visible light spectrum, measured in wavelengths, is the range of electromagnetic radiation we can see. It is outlined in color spectrum charts.

Red light therapy is a deeply studied science, here you'll find links to several studies highlighting the health benefits of light therapy.

Albert Einstein won his Nobel Prize in Physics in 1921 "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect" [ nobelprize.org ]. The photoelectric effect, in part, describes the energetic response from photons and electrons reg
