Combining science and design to measure our exposure to light

Daylight plays an essential role in sleep, alertness and hormone regulation. EPFL has joined forces with Geneva School of Art and Design (HEAD—Genève) to develop a wearable sensor that measures how much light an individual ...

Light

Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm, or perhaps 380–750 nm.) In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.

Three primary properties of light are:

Light, which exists in tiny "packets" called photons, exhibits properties of both waves and particles. This property is referred to as the wave–particle duality. The study of light, known as optics, is an important research area in modern physics.
