Statement 2: Intensity of image is reduced when We cover the half of a convex lens with a black paper.

A

Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.

B

Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.

C

Statement 1 is true but statement 2 is false.

The correct Answer is:
To solve the question, we need to analyze the two statements provided and determine their validity. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - The statement claims that even when half of a convex lens is covered with black paper, the lens will still produce a complete image. - A convex lens can bend light rays that pass through it. When half of the lens is covered, the uncovered half can still refract light rays from an object and create an image. - Therefore, this statement is **true**. A complete image can still be formed using the rays that pass through the uncovered part of the lens. 2. **Understanding Statement 2**: - This statement asserts that the intensity of the image is reduced when half of the convex lens is covered with black paper. - When half of the lens is covered, only the rays passing through the uncovered portion contribute to the image formation. Since fewer rays are available to form the image, the overall brightness or intensity of the image will indeed be reduced. - Hence, this statement is also **true**. 3. **Analyzing the Relationship Between the Statements**: - Statement 1 is about the ability of the lens to form a complete image despite half being covered, while Statement 2 discusses the reduction in intensity due to the covering. - Although both statements are true, Statement 2 does not explain Statement 1. The formation of a complete image does not depend on the intensity of the image but rather on the ability of the lens to refract light. 4. **Conclusion**: - Both statements are true, but Statement 2 does not serve as an explanation for Statement 1. Therefore, the correct option is that both statements are true, but Statement 2 is not the correct explanation of Statement 1. ### Final Answer: Both statements are true, but Statement 2 is not the correct explanation of Statement 1. ---
