Question

Assertion (A): The rainbow is a natural spectrum of sunlight in the sky.
Reason (R) : Rainbow is formed in the sky when the sun is overhead and water droplets are also present in air.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false, but Reason (R) is true.

Answer 1

The Correct Option is C

Step 1: Understanding the Assertion (A):
The assertion states that the rainbow is a natural spectrum of sunlight in the sky. This is true because a rainbow is indeed formed when sunlight is refracted, reflected, and dispersed through water droplets in the atmosphere. As the light passes through these droplets, it splits into its component colors, forming the natural spectrum we see as a rainbow.

Step 2: Understanding the Reason (R):
The reason provided suggests that a rainbow is formed when the sun is overhead and water droplets are present in the air. This is not entirely accurate.
- While it is true that water droplets are necessary for the formation of a rainbow, the sun being overhead does not lead to the formation of a rainbow.
- A rainbow is visible when the sun is low in the sky (in the early morning or late afternoon), and the observer is positioned such that the sunlight strikes the water droplets at the correct angle. When the sun is directly overhead, the light passes straight down, making it impossible for a rainbow to form.

Step 3: Analyzing the Correctness of the Answer:
- Assertion (A) is true: The rainbow is indeed a natural spectrum of sunlight, which is a correct description of a rainbow.
- Reason (R) is false: The reason that the rainbow is formed when the sun is overhead is incorrect because a rainbow requires the sun to be low in the sky (early morning or late afternoon), not overhead.

Conclusion:
The correct answer is: Assertion (A) is true, but Reason (R) is false.
