colours and filters / opaque

colours work on wavelengths being

absorbed transmitted and reflected

white light is all the colours what happens looking at a red apple

red is reflected everything else absorbed

black objects /white objects

absorb all wavelengths /reflect all equally

filters only

transmit certain light if it`s not that the object will be black

why will certain objects be black if the object colour is not the same as the filter colour

as filters filter out different wave lengths leaving one colour transmitted and rest absorbed

opaque objects do not … instead they…

transmit light… reflect and absorb

for opaque objects reflecting not primary colours that means they are reflecting

a mixed of primary colour wavelengths
