Wave property of light

Wave property of light. Waves can carry energy Wavelength ( l ) : distance between successive crests (or troughs) Frequency (f): # of waves passing a point in 1 second Wave speed (v): wavelength x frequency v = l x f v sound = 340 meters/second v light = 3x10 8 meters/second.

Human eye is sensitive 380 < l < 700 nm l < 300 nm (UV) is absorbed mostly

Human eye is sensitive 380 < l < 700 nm l < 300 nm (UV) is absorbed mostly by cornea and l > 1200 nm by aqueous humor. Green cell (most sensitive for 520 nm), and 2 other types of cells sensitive to shorter and longer wavelength sense light and send signal to brain.
