The Light

Beam of light


Beams of light coming from a light source can be divergent, convergent or parallel. Find examples of parallel rays in addition to the sun's rays.

Molecules and light


Turn on the light source to explore. Watch what happens in the observation window as you set up different combinations of light source and molecule. This simulation has a zoom function, so you can enlarge sections of the simulation for a closer look, if necessary.

Color vision


Create a rainbow by combining red, green and blue light. Change the wavelength of a monochromatic beam or white light filter. See light as a solid beam, or as individual photons.
