Expert Solution & Answer

Answer to Problem 1CQ

The reason why the moon shadow has a dark center surrounded by a region of increasing brightness is been explained.

Explanation of Solution

During the solar eclipse, the moon comes in between the sun and the Earth. The rays coming from the sun will strike the moon’s surface and form a region of dark circle in the Earth’s surface called umbra as shown in Figure 1.

College Physics: A Strategic Approach (3rd Edition), Chapter 18, Problem 1CQ

Some part of the rays strikes the moon and reaches the Earth’s surface causing dark spots (umbra). The other rays coming from the sun will not be blocked by the moon and form bright spots (penumbra) on the Earth’s surface.

Conclusion:

Thus, the reason why the moon shadow has a dark center surrounded by a region of increasing brightness is been explained.
