When light hits a white piece of paper, the paper reflects most of the light across the entire visible spectrum. This reflection is what makes the paper appear white to our eyes, as it doesn't absorb any specific color wavelength and instead reflects all wavelengths equally.
If you put a piece of white paper under a green light all that will happen is the paper will turn green. The only time this will vary is if you have special ink that will show up under certain colored light.
The paper appears dark because red light is absorbed by the blue pigment, not reflected. The blue pigment absorbs red light and reflects blue light, which is why the paper appears blue under white light.
A white piece of paper reflects all colors of visible light equally, which is why we perceive it as white. It does not absorb any specific colors, enabling it to reflect a full spectrum of light.
Yes, light reflects more on a mirror than on a white piece of paper because mirrors have a smooth, shiny surface that allows light to bounce off at the same angle. In contrast, the rough and non-reflective surface of a white piece of paper scatters light in different directions, absorbing some of it.
The black ink absorbs most of the white light, reflecting very little back to our eyes. This absorption is what makes the ink appear black. The white paper reflects all colors of the white light, creating the contrast between the black ink and the paper.

White surface reflects all wavelengths of visible light spectrum (ie. white color is a mixture of all the other colors). If the light that falls on the surface has one specific wavelength, only that wavelength occurs in the light reflected.
When red and green lights are shone onto a white piece of paper, the paper appears yellow. This is because red and green light mix to create yellow light when they are combined. The paper reflects the yellow light back to our eyes, making it appear yellow.
Depending on the source of the heat energy: -A darker piece of paper would absorb more energy from light sources, then a white piece of paper. This is due to the fact that the white piece of paper would reflect most of the light energy, whereas the dark paper would absorb that energy. This light energy can then be converted into heat energy, leading the dark paper to have more heat energy then the white paper -Heat from a source such as hot water being poured on the paper, would not lead to any color related heat difference
The reflectance curve for a white piece of paper would show high reflectance across the visible spectrum, especially in the shorter wavelengths corresponding to blue and green light. This indicates that the paper is reflecting most of the incident light, giving it a bright and white appearance.
A piece of paper appears white because it reflects all visible light wavelengths, giving it a neutral color. This means that all colors of light are equally reflected off the paper's surface, resulting in the perception of white.
The white paper appears red under a red light because the paper is reflecting and absorbing certain wavelengths of light. When red light shines on the paper, the paper reflects the red light and absorbs other colors, making it appear red.
