Question

Assume the light wave directed at the paper is white light and the paper contains pigments that absorb the wavelengths of red-orange-yellow-green-blue-indigo-violet. What color will the paper appear to human eyes? Assume the light wave directed at the paper is white light and the paper contains pigments that absorb the wavelengths of red-orange-yellow-green-blue-indigo-violet. What color will the paper appear to human eyes? A) black B) brown C) green D) white
It is D) WHITE

Answer 1

Answer:

It would appear to be black because the paper is absorbing all the colors. Black is the absence of color.

Answer 2

Answer:

The correct answer will be option-A

Explanation:

The visible light that travels in the atmosphere and perceived by humans appears as a white light which lies between wavelength range of 400 to 700nm.  Newton showed that white light is composed of seven different colors called red-orange-yellow-green-blue-indigo-violet (VIBGYOR).

In the given question, if the paper contains the pigments which absorb all these colors then the light perceived by the eye will appear black as all the wavelength of light gets absorbed by the pigments.

Thus, option-A is the correct answer.
