With reference to the Lunar Eclipse, consider the following statements...
A total lunar eclipse will occur on 8 November, 2022. The eclipse is visible from all places of India at the time of Moonrise.
- An eclipse of the Moon (or lunar eclipse) can only occur at Full Moon – when Earth is located directly between the Sun and the Moon –, and only if the Moon passes through some portion of Earth's shadow.
- That shadow is composed of two cone-shaped components -
- The outer or penumbral shadow is a zone where the Earth blocks part but not all of the Sun's rays from reaching the Moon.
- The inner or umbral shadow is a region where the Earth blocks all direct sunlight from reaching the Moon.
- Types: Astronomers recognize three basic types of lunar eclipses –
- Penumbral Lunar Eclipse: The Moon passes through Earth's penumbral shadow. These events are of only academic interest because they are subtle and hard to observe.
- Partial Lunar Eclipse: A portion of the Moon passes through Earth's umbral shadow. These events are easy to see, even with the unaided eye.
- Total Lunar Eclipse: The entire Moon passes through Earth's umbral shadow. These events are quite striking due to the Moon's vibrant red colour during the total phase (totality).
Hence only statement 1 is correct.

With reference to the Lunar Eclipse, consider the following statements...
Explanation:
The given statements are related to the Lunar Eclipse, which occurs when the Earth comes between the Sun and the Moon, causing the Moon to pass through Earth's shadow. Let's analyze each statement individually:
Statement 1: The Moon passes through Earth's penumbral shadow is known as Penumbral Lunar Eclipse.
- The Earth's shadow consists of two parts: the penumbra and the umbra.
- The penumbra is the outer part of the shadow, where only a portion of the Sun's light is blocked. It creates a faint shadow and does not completely obscure the Moon.
- When the Moon passes through the Earth's penumbral shadow, it results in a penumbral lunar eclipse.
- During this type of eclipse, the Moon appears slightly dimmer but does not darken significantly.
- Therefore, statement 1 is correct.
Statement 2: A portion of the Moon passes through Earth's umbral shadow is known as Total Lunar Eclipse.
- The umbra is the inner part of the Earth's shadow, where all direct sunlight is blocked. It creates a dark, cone-shaped shadow.
- When the Moon enters the Earth's umbra, it results in a total lunar eclipse.
- During a total lunar eclipse, the Moon appears dark red or orange because some sunlight is refracted by the Earth's atmosphere and reaches the Moon.
- Therefore, statement 2 is incorrect as it refers to a total lunar eclipse, not a portion of the Moon passing through the Earth's umbral shadow.
Conclusion:
- From the explanation above, we can conclude that statement 1 is correct, but statement 2 is incorrect.
- Therefore, the correct answer is option 'A' - 1 only.
