Document Summary
Electromagnetic energy creates a spectrum described as wavelengths (how long a wave is) Humans can only detect the visible light (only humans, some animals can see into the infrared or ultraviolet) Depending on the detectors that the animal/human has. We can have things that can detect the light, but we have to convert into energy that we can visually process (ex: tv, radars, radio) We can see 400-700 nanometers of the visual spectrum (humans) Most perceived light is reflected light (ex: looking straight at a lamp/projector light: photons of light being blasted onto surfaces, sometimes it is consumed by the surface and the rest is transmitted to your eye. Cornea=protect the eye and focus light (focus 60-80% of light), no muscles attached, doesn"t change/move (aka: fixed objects like a magnify glass) Aqueous humor= very thin body layer behind the cornea.
