A real image is formed by a convex lens, then it is put in contact with a concave lens and again a real image is formed. This image will

Solution:

Convex Lens:

A convex lens (converging lens) has the property of converging parallel rays of light to a focal point. The real image formed by the convex lens is inverted and can be projected on a screen.

Concave Lens:

A concave lens (diverging lens) has the property of diverging rays of light that pass through it. When placed in contact with a convex lens, it alters the focal length of the system.

Combined Lens System:

• The focal length of the combination of a convex lens and a concave lens can be calculated using the lens formula: 1/f effective = 1/f convex + 1/f concave
• If the combined focal length is positive, the system still acts as a converging lens and can form a real image.
• The position and nature of the final image depend on the object distance, focal lengths of the lenses, and their relative positions.
