A virtual image produced by a lens is always D. located in the back of the lens. A virtual image is an optical image formed due to apparent divergence of light rays from a point and is not due to the actual divergence of the rays. This image cannot be projected on a screen

A virtual image produced by a lens is always C) located in front of the lens.

Further Explanation

When incident rays pass through a lens they may converge or diverge upon refraction depending on the type of lens. A convex lens is thicker in the middle than at the edges and are converging lenses. Light rays that pass through the lens meet or converge at a certain point. In contrast, concave lenses are diverging lenses - once light passes through them, they spread out. Concave lenses are thinner in the middle than at the edges.

The point where refracted rays converge is where the image forms. There are two types of images: virtual and real.

Real images are formed where the refracted rays actually meet or converge. They are always oriented upside down. When a plane surface like a screen is placed at this point, the real images will be visible like how a projector works.

Virtual images are formed when the refracted rays are diverging. They are upright and called ‘virtual’ because they form at a point that is determined by tracing the diverging rays backward. The refracted rays don’t actually meet at this point. This is why putting a screen at this point will not make the image visible.

The size of the real and virtual images depend on the kind of lens and the distance of the object from the focal point.

A. larger than the object - FALSE since this statement is only true if the lens is convex and the object is between the focal point and the lens. Since the type of lens is not stated, this statement is not absolutely true.

B. smaller than the object -  FALSE because this is only true if the lens is concave

C. located in front of the lens - TRUE. The side where the object is (or where light is incident) is considered the “front side” and the opposite is the “back”. Whether the lens is concave or convex, the virtual image will form in front of the lens or at the same side where the object is.

D. located at the back of the lens  - FALSE. Real images form at the back of the lens following the convention stated in option C.
