Q. Which of the following can produce virtual images?

1. Concave lenses
2. Convex lenses
3. Concave mirrors
4. Convex mirrors
5. Plane mirrors

Select the correct option from the codes given below:
Answer: 1, 2, 3, 4 & 5
Notes: Concave lenses always form virtual images. Convex lenses produce virtual images when the object is within focal length. Concave mirrors produce virtual images when the object is between focal point and mirror. Convex mirrors and plane mirrors always form virtual images. Thus, all five can produce virtual images under suitable conditions.
