Chapter 28, Problem 25A

To determine

The color of tennis ball.

Answer to Problem 25A

The color of the tennis ball is yellow-green because the human eye is most sensitive to this color.

Explanation of Solution

Introduction:

The color of opaque objects is the color of light that is reflected by it.

Despite of the official proof that tennis ball is yellow, it has observed that some people see the tennis ball to be green in color. If the color spectrum is observed, it is concluded that humans perceive wavelength of green light from 520 to 560 nm and the wavelength of yellow light from 560 to 590 nm. Hence, the measurement of light reflected from the tennis ball depicts that the color of the tennis ball is actually yellow-green.

Hence, the color of tennis ball is yellow-green because the human eye is most sensitive to this color.

Conclusion:

The color of the tennis ball is yellow-green because the human eye is most sensitive to this color.
