Physics 251 Conceptual Questions(with Correct answers)
ch.18.1: 
During a solar eclipse, the 
sun—a small but extended 
source—casts a shadow of the 
moon on the earth. Explain 
why the moon's shadow has 
a dark center surrounded 
by a region of increasing 
brightness. correct answersAnswer: 
 
The moon acts to re-reflect some of the light coming from the lighter part of the Earth. The closer to the center the darker due to there being less re-reflected light shining on the Earth.
