I think, what we see is the light reflected from an object .' If the object has certain colour then only that colour is reflected back to our eyes and we see that'. I want to know if it is right or not.
*If right then what happens to the rest of the color which are not reflected. If they are absorbed by the light then where do they go.
*If not then what is the colours that we see?
(Please read the question carefully before answering)
Thank you
