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?
Light reflects better off a mirror than a sheet of paper because mirrors have a smooth, shiny surface that allows light to bounce off without scattering. In contrast, paper has a rough and absorbent surface that absorbs and scatters light, resulting in less reflection.
A sheet of red paper will look black when illuminated with what color light?
A sheet of red paper will look black when illuminated with green light. This is because red paper absorbs green light, preventing any reflection of light that would allow us to see the red color.
A sheet of red paper will look black when illuminated with what light?
A red sheet of paper will appear black when illuminated with cyan light, which is the complementary color of red. When the paper is exposed to cyan light, it absorbs all the complementary color wavelengths and reflects none, making it appear black.
How you calculate weight of acrylic sheet eg 5mm perspex?
To calculate the weight of an acrylic sheet, you can use the formula: weight = area x thickness x density. The density of acrylic is around 1.19 g/cm³. So, if you have a 5mm thick acrylic sheet with dimensions 1m x 1m, the weight would be: 1m x 1m x 0.5cm x 1.19 g/cm³ = 595 grams.
Which has the lowest albedo A black sheet of paper A white sheet of paper The surface of a body of water or A mirror?
A black sheet of paper has the lowest albedo because it absorbs most of the light that hits it, reflecting very little back. Albedo is the measure of how much light is reflected by a surface, with higher albedo indicating more reflection.
