Question

In which lens can both real and virtual images be formed?

• A. Convex lens
• B. Concave lens
• C. Both (A) and (B)
• D. None of these

Hint:

Convex lenses are used in cameras, projectors (real images) and magnifying glasses (virtual images).

Answer 1

The Correct Option is A

Step 1: Lens Types and Their Images:
Lenses bend light rays due to refraction. Their ability to form images depends on their shape.
Convex lens (converging lens): Can form both real and virtual images depending on the object’s position.
Concave lens (diverging lens): Always forms virtual, erect, and diminished images.
Step 2: Behavior of Convex Lens:
If the object is placed beyond 2F, the image is real, inverted, and smaller.
If the object is at 2F, the image is real, inverted, and same size.
If the object is between F and 2F, the image is real, inverted, and magnified.
If the object is between F and the lens, the image is virtual, erect, and magnified.
Step 3: Conclusion:
Thus, only convex lenses can form both types of images (real & virtual).
Step 4: Final Answer:
The correct lens is the Convex lens.
