Question

Arrange the following phases of a total solar eclipse in their correct chronological sequence:
A. Mokshah (Release)
B. Sparshah (First Contact)
C. Sammilanam (Total Immersion)
D. Unmilanam (Emergence)
E. Madhyam (Maximum Phase)

• A. A, D, B, C, E
• B. D, C, E, B, A
• C. A, B, E, C, D
• D. B, C, E, D, A

Hint:

Sparsha (Touch) $\rightarrow$ Moksha (Freedom). These are the bookends of every eclipse. Middle (Madhya) always happens between the start and the end.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
An eclipse is a dynamic event with specific geometric milestones. Astronomers calculate the timing of these contacts to predict the duration and magnitude of the eclipse.

Step 2: Defining the Phases:
1. Sparshah (B): The moment the Moon's disk first touches the Sun's disk. This is the start of the eclipse.
2. Sammilanam (C): For a total eclipse, this is the moment the Sun's disk is completely covered by the Moon. The period of totality begins here.
3. Madhyam (E): The middle of the eclipse, when the centers of the Sun and Moon are at their minimum distance. The magnitude is greatest at this point.
4. Unmilanam (D): The moment the Sun's disk first reappears from behind the Moon. Totality ends here.
5. Mokshah (A): The final contact, when the Moon's disk completely leaves the Sun's disk. The eclipse ends.

Step 3: Sequencing:
The natural progression is B (First contact) $\rightarrow$ C (Full cover) $\rightarrow$ E (Middle) $\rightarrow$ D (Emergence) $\rightarrow$ A (Final release).

Step 4: Final Answer:
The correct sequence is B, C, E, D, A.
