Light is more than what we see. The Sun sends out a number of waves of light in different wavelengths. Find out about wavelengths and the electromagnetic spectrum.

Color is determined by a wavelength, your eyes, and your brain. What are light and color? It all starts with the Sun. The Sun puts out a lot of different waves of light, some of which we can see ...

This illustration, of light passing through a dispersive prism and separating into clearly defined ... More colors, is what happens when many medium-to-high energy photons strike a crystal.

The electromagnetic spectrum has many types of light waves. It includes radio waves, microwaves, infrared light, visible light, ultraviolet, X-rays, and gamma rays. Each type of light has a different ...

As a solar eclipse approaches totality and our eyes adjust to dimming light, our color vision changes. It’s called the Purkinje effect.

Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to ...
