Question

Which of the following statement(s) is/are correct?

I. An image that can be obtained on a screen is called a virtual image.
II. A convex lens always forms a virtual image.
III. A concave lens always forms a virtual image.

• A. Only II
• B. Only III
• C. I and III
• D. I, II, and III

Answer 1

The correct option is B Only III

An image that can be obtained on a screen is called a real image, whereas an image that cannot be obtained on a screen is called a virtual image.

An image formed by a convex lens can be real or virtual depending on the distance between the object and the lens. But on the other hand, an image formed by a concave lens is always virtual, erect, and diminished in size.
