A partial lunar eclipse occurs when the Moon is located _____ region.

• A. outside earth‘s shadow​
• B. in both umbra and penumbra​
• C. in only umbra​
• D. in only penumbra​

Answer 1

The correct option is B in both umbra and penumbra​

• When the earth comes in between the sun and the moon, the earth casts its shadow on the moon.
• The part of the moon which lies within the umbra of the earth, will not be visible from the earth. Thus, the lunar eclipse takes place.
• But if they are slightly out of line( in both umbra and penumbra, only a part of the moon is in the penumbra of the earth and a partial lunar eclipse occurs.
• Hence the answer will be Option C - both umbra and penumbra
