Which one of the following statements regarding lenses is not correct?
Options
- AA convex lens produces both real and virtual images
- BA concave lens produces both real and virtual images.
- CA convex lens can produce images equal, greater and smaller than the size of the object.
- DA concave lens always produces images smaller than the size of the object.
Correct answer
B. A concave lens produces both real and virtual images.
Step-by-step solution
Concave lenses refract parallel light waves, causing them to disperse. The three light rays traveling into the concave lens shown above travel away from each other. For this reason, concave lens are also called diverging lenses. As a result of this light divergence, concave lenses create only virtual images.
