A real image produced by a convex lens can be projected onto a screen.

A real image produced by a convex lens can be projected onto a screen.

• A. Can be projected
• B. Cannot be projected
• C. Always upright
• D. Always magnified

Answer: (A)

Light actually converges to a point when a convex lens forms a real image. Because the rays physically meet at that location, a screen placed there will intercept the converging rays and reveal a sharp image. This is why a real image can be projected. The real image occurs when the object is beyond the focal length, and it is usually inverted with magnification that depends on the object–image distances. Real images are not guaranteed to be upright or magnified; those properties vary with distance. In contrast, when the object is within the focal length, the image is virtual and cannot be projected onto a screen.
