To determine

To Choose: The correct option.

Answer to Problem 5STP

Correct option is (D).

Explanation of Solution

Introduction:

Color subtraction is a useful method to determine the color appearance of the object if the color of the pigments and light are known.

If the complementary color scheme is used, then the color of light absorbed by the given material can be determined.

Consider that the white light has three main primary colors i.e. red, blue, and green. If the white light is reflecting on the shirt then green, blue, and red light is also shining on the shirt. If the blue light is absorbed by the shirt, then only green and red light will be reflected by the shirt and when these colors strikes on the eyes, they give appearance of yellow color due to which shirt appears yellow. This is the process of the color subtraction.

It is clear that the final color depends on the colors reflected by the shirt.

Now from the above discussion it is clear that the correct option is (D): the color that an object appears to be is a result of the material absorbing specific light wavelength and reflecting the rest.

Conclusion:

(D) is the correct option
