Yes, it is a correct statement that a convex lens of focal length 20 cm can produce a magnified virtual as well as real image. The position of the object with respect to the lens determines the nature and position of the image formed.
For a magnified virtual image:
- The object should be placed between the focus and the lens.
- The image formed will be virtual, erect, magnified and located on the same side of the lens as the object.
- The image size will be larger than the object size.
For a magnified real image:
- The object should be placed beyond 2F (twice the focal length) from the lens.
- The image formed will be real, inverted, magnified and located on the opposite side of the lens as the object.
- The image size will be larger than the object size.
Explanation:
- The convex lens has two spherical surfaces, one of which is convex and the other is concave.
- When a parallel beam of light falls on a convex lens, it converges the light rays to a point on the other side of the lens, known as the focus.
- The distance between the lens and the focus is called the focal length.
- The position of the object with respect to the lens determines the position and nature of the image formed.
- If the object is placed between the focus and the lens, the image formed is virtual, erect and magnified.
- If the object is placed beyond 2F, the image formed is real, inverted, magnified and located on the opposite side of the lens.
