Light and Color 07/10/2008 12:50:00 REVIEW FROM 08.28.08 We can see different objects around us because  Some of them can reflect or scatter light that enters our eyes Some of them can emit light that enters our eyes  The following waves propagate in free space Light  What does Alex see when the wave at left with wavelength 650 nm goes by what  does he see? Nothing How do we see each other in the classroom? Some of the ambient light reflects from our colleagues and enters our eyes We see color when waves of different wavelengths enter our eyes.  We can see  different wavelengths than others.   Light with wavelength 650 nm appears red when it enters a viewers eye Light with wavelength of 520 nm appears green when it enters a viewers eye Light with wavelength of 470 nm appears blue when it enters a viewers eye. What is white light?  A combination of all different colors.
