Lucianne Walkowicz: Light waves, visible and invisible

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. [Directed by Pew36 Animation Studios, narrated by Lucianne Walkowicz].
