Chapter 5, Problem 11STP

To determine

To Describe: The color of a material related to its absorption and the reflection of radiant energy.

Answer to Problem 11STP

A white light or sunlight contains seven hidden colors which can be seen due to absorption and reflection through the other objects.

Explanation of Solution

Introduction:

A white light contains violet, indigo, blue, green, yellow, orange and red colors in its electromagnetic spectrum.

In absorption, the some of the colors of the lights are absorbed like in a dark room, no color has been visible. This is because of absorption of all the colors. When light falls on red glass, then all the colors except red gets absorbed. And so, only red color of white light becomes visible. Similarly in reflection, when a white reflected from a prism or glass then it may emit different color based on its property.

Conclusion:

Hence, a light contains electromagnetic spectrum in which colors can be seen due to absorption and reflection through other objects.
