Where is the real image located when a convex lens forms a real image?

• A. On the opposite side from the object.
• B. On the same side as the object.
• C. Behind the lens.
• D. At the lens.

Answer: (A)

A real image is formed where the light rays actually converge after passing through the lens. For a convex lens, when the object is placed beyond the focal length, the refracted rays meet on the side of the lens opposite the object. That convergence point is the real image, and it can be projected onto a screen. If the object is within the focal length, the rays don’t converge on that opposite side but instead appear to come from a point on the same side as the object, giving a virtual image. So the location opposite the object is the correct description for where a real image is formed.
