Lucianne Walkowicz: Light waves, visible and invisible (2013x577)

Date de diffusion: Sept 19, 2013

Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our perception. Lucianne Walkowicz shows us the waves we can't see.
