Chapter 9: Problem 4

The cover of a book appears blue when illuminated with white light. What color will it appear in blue light? Red light? Explain.

Short Answer

Expert verified
Answer: The book cover will appear blue under white light and blue light, and it will likely appear black or very dark under red light.

Step by step solution

01

Understanding color subtraction

Color subtraction is the concept that when a colored object is illuminated by a light source, the object will absorb certain colors (wavelengths) of light and reflect the others. In this case, the book cover appears blue under white light because it absorbs other colors and reflects blue light.
02

The color of the book cover under blue light

Since the book cover appears blue under white light, we can infer that it reflects blue light. When illuminated with blue light, the book cover will still reflect blue light, as it does not absorb this color. Therefore, the book cover will appear blue under blue light.
03

The color of the book cover under red light

As we know, the book cover appears blue under white light as it reflects blue light and absorbs other colors. When illuminated with red light, the book cover will absorb this color since it is not blue. As a result, the book cover will likely appear black or very dark in red light, as it is not reflecting any light that our eyes can perceive.
