Quizplus · Accepted Answer

The paper appears red because it reflects the red wavelength of light and absorbs all other visible wavelengths. This means that the paper is not emitting any light on its own, nor is it dispersing white light. Choice A is incorrect because the paper is absorbing red light, not reflecting it. Choice B is incorrect because the paper is not emitting any light. Choice D is also incorrect because the paper is not dispersing white light, it is only reflecting the red wavelength.
