Question

Which of the following is true in case of a concave lens?

• A. Erect and virtual image
• B. Inverted and virtual image
• C. Erect and real image
• D. Inverted and real image

Answer 1

The Correct Option is A

To solve the problem, we need to determine the type of image formed by a concave lens.

1. Understanding the Image Formation in a Concave Lens:
A concave lens is a diverging lens, which means it causes parallel light rays to diverge after passing through the lens. The image formed by a concave lens has the following characteristics:

• Erect: The image formed by a concave lens is always upright (erect), regardless of the object's position.
• Virtual: A concave lens forms a virtual image because the diverging rays appear to converge on the same side of the lens as the object.
• Smaller: The image formed is always smaller than the object, and it cannot be projected onto a screen.

2. Conclusion:
The correct description of the image formed by a concave lens is that it is erect and virtual.

Final Answer:
The correct answer is (A) Erect and virtual image.
