On which day can a lunar eclipse be seen?

Correct option is B

The correct answer is option (b) On the day of Purnima (Full Moon)

Explanation

A lunar eclipse can only occur on the day of Purnima (the Full Moon). This is when the Earth is positioned between the Sun and the Moon, causing the Earth's shadow to fall on the Moon, creating a lunar eclipse.

• Amavasya refers to the New Moon phase, when the Moon is positioned between the Earth and the Sun, and hence, a lunar eclipse is not possible.

• A lunar eclipse is a rare event and does not occur regularly on specific days of the week, like the first Sunday or the first day of the Indian calendar month.

Information Booster

• A lunar eclipse can only occur when the Moon is in the opposite side of the Earth from the Sun, i.e., during a full moon.

• During a lunar eclipse, the Earth’s shadow completely or partially blocks the Sun’s light from reaching the Moon.

• A solar eclipse, in contrast, occurs during the new moon phase when the Moon blocks the Sun's light from reaching the Earth.

Additional Knowledge

• Purnima: This is the day when the Moon is fully illuminated, and the Earth can cast its shadow on the Moon.

• Amavasya: A new moon day when the Moon is not visible from Earth and cannot cause a lunar eclipse.
