Question

Quizplus · Accepted Answer

When sunlight illuminates a page from a Conceptual Physics book, the page reflects some of the light and also absorbs some of the light, particularly at the text lettering. The paper of the book reflects some of the incident light due to its smooth surface and may also diffuse some of it due to its intrinsic roughness. However, the ink used for printing the text absorbs a significant portion of the light in the visible spectrum, depending on its color and opacity. This is why the text appears darker than the surrounding paper and why reading is possible in the first place.
