What color light will make a red sheet of paper look black?
Any light that does not contain the primary color red will make the sheet of paper look black. (for example green, blue, cyan,... but not yellow, violet,...) This is because the surface of the sheet is such that it absorbs all the colors of white light except red which is reflected and which is why it appears red in white light.
Why does light reflect better off a mirror than a sheet of paper?
Paper absorbs the light, but the shiny surface of the mirror reflects it.
What is do you use dampalon transparent sheet for?
well dampalon is a polycarbonate material used fr roofing and facade treatments.....a translucent and a very light acrylic material .
An activity to show that the incident ray the reflected ray and the normal at the point of icident ray lie in the same plane?
Place a plane mirror on the table. Take a paper sheet and make a small hole in its centre. Make sure that the light in the room is not bright. Hold the sheet normal to the table. Take another sheet and place it on the table in contact with the vertical mirror. Draw a normal line on the second sheet from the mirror. Now, light a torch on the mirror through the small hole such that the ray of light falls on the normal at the bottom of the mirror. When the ray from this hole is incident on the mirror, it gets reflected in a certain direction. You can easily observe the incident ray, reflected ray and the normal to the mirror at the point of incidence on the sheet placed on the table. This shows that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane.
Why is it that a sheet of white paper is a good reflector of light?
That's the definition of "white" - that it reflects a large percentage of the incoming light (all colors get reflected by more or less the same percentage).

Why an exssecively thin film appears black in the reflection of light?
Destructive interference. If the sheet is very thin, near half the wavelength of the incident light then light reflected from the top layer is out of phase with light reflected from the bottom layer. These two reflected light waves will cancel each other out.

Paper absorbs the light, but the shiny surface of the mirror reflects it.
