Question

Assertion: It is not possible to see a virtual image by eye.

Reason: The rays that seem to emanate from a virtual image do not in fact emanates from the image.

• A. Both assertion and reason are true
• B. Both assertion and reason are false
• C. The assertion is true but the reason is false
• D. The assertion is false but the reason is true

Answer 1

The correct option is D

The assertion is false but the reason is true

Option (D): The assertion is false, but the reason is true

Explanation for the Assertion: It is not possible to see a virtual image by eye.

1. As the name indicates, virtual images are different from real images.
2. As the image is not real, that is, the rays do not focus on a point, these images cannot be shown on a screen.
3. A virtual image can be formed with a diverging lens or a convex mirror as the rays are converging in their extension.
4. It is possible to form these images with the help of a converging mirror or concave mirror, only if the object is within the focal length.
5. The human eye can see the virtual image if the object is placed within the focal length of the eye.

Explanation for the Reason: The rays that seem to emanate from a virtual image do not in fact emanates from the image.

1. It can be said that the light rays appear to emanate from the virtual image but do not actually exist at the position of the virtual image.
2. Thus an image cannot be seen by placing a screen at the position of the virtual image.
3. Hence, we can say that the rays that seem to emanate from a virtual image do not in fact emanates from the image.

Thus, the assertion is false but the reason is true.
