I didn't read anything about it recently.I just thought about it. I heard that every metal(which is used for coating) absorbs some ray,thats why they can't give 100% reflection.So,I want to know which metal can give maximum reflection?And do the coating have any impact on image?

Which metal platings on glass will provide 100% reflection as a mirror? In which case we will get an brighter image than the actual one in mirror?And in which case it will be darker?Which metal(used for platings) will absorb a very little amount of ray? Can anyone give the explanation?

Can you tell it in more details?

When we touch the screen of a mobile or laptop we can see some colors on the sweat adhered to the screen.Which property of light can explain it? Is it for interference or for refraction?
