Chapter 24, Problem 32Q

To determine

To identify: Whether the sunlight would be white or would it be of some other color for the given situation.

Answer to Problem 32Q

Sunlight would be redder than it is now, if the Earth’s atmosphere is 50 times denser than it is.

Explanation of Solution

Introduction:

When light travels from one medium to another medium, then, part of the light gets absorbed by the particles of the previous medium. This phenomenon is known as scattering of light.

As the density of the atmosphere is increased 50 times than it is. The blue light will be scattered away more and more in all the directions. Hence, the light that reaches the ground will become redder as the color of a deep red sunset.

Conclusion:

Hence, the sunlight would be redder, if the earth’s atmosphere is 50 times denser than it is.
