how to differentiate between colours within the visible light spectrum
each colour has their own band of wavelength and frequency
for example...
blue has a shorter wavelength and higher frequency than red
the two types of reflection
specular, diffuse
what is specular 
smooth surface which gives a single reflection
what is diffuse 
reflection off a rough surface that causes scattering
how do colour filters work
the filter absorbs every other colour, and only letting a certain wavelength through
how do colours appear opaque
if all wavelengths reflect - white colour
if all wavelengths are absorbed - black colour
the wavelength which is absorbed - the colour it appears
objects that transmit light are either...
transparent or translucent - scatter most light and only let some through
