Question

Assertion (A): A convex lens is used as an objective lens of a telescope.

Reason (R): Convex lens, converges parallel rays coming from stars.

Options

• Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

• Both Assertion (A) and Reason (R) are true but Reason (R) is not the correct explanation of Assertion (A).

• Assertion (A) is false, but Reason (R) is true.

• Assertion (A) is true, but Reason (R) is false.

Answer 1

Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of Assertion (A).

Explanation:

The assertion is true because a telescope uses a convex lens as its objective lens. The reason is also true because the lens converges the nearly parallel rays from distant stars to form an image.
