Скачать или смотреть Is 1 AU Greater Than 1 Light Year? | Assertion Reasoning Solved | JEE NEET CET | SCC Simplify Physic

📘 Welcome to SCC – Simplify Physics by Shinde Sir

In this short video, we tackle an important Assertion and Reasoning question often asked in competitive exams.


---

Assertion: One Astronomical Unit is greater than one Light Year
Reason: An Astronomical Unit is the average distance between Earth and the Sun

Let’s test both statements using correct values of AU and Light Year.


---

📐 Concept Breakdown:

1 AU = 1.496 × 10¹¹ meters

1 Light Year = Distance traveled by light in one year
= Speed of light × Time
= 3 × 10⁸ m/s × 365.25 × 24 × 3600 seconds
= 9.46 × 10¹⁵ meters


So clearly:
1 Light Year is much greater than 1 AU


---

✅ Final Answer:

Assertion is False

Reason is True


Correct Option is:
Assertion is False, but Reason is True
