An object is placed in front of a lens which forms an image of the object.

AIf the lens is convex, the image cannot be virtual.
BIf the image is real, then it is also inverted.
CIf the image is real, then it is also upright.
DIf the image is virtual, the lens must be a diverging lens.
EIf the image is virtual, then it is also inverted.

An object is placed in front of a lens, which forms an image of the object. If the lens is convex, the image cannot be virtual. The correct option is A.

What is a lens?

A lens is an object of glass. There are different types of lens, convex and concave. It is a transmission optical device. When a beam of light reflect on the lens, the light go through it and make the object look bigger or smaller.

Convex lens is thicker in the center and thin in the edges and these lenses are these lenses are made of the two spherical lenses. The image made by this lens is virtual, not inverted.

Convex lens are used in magnifying glasses, and it makes the object look bigger. And the lens will be shorter than the focal length.

Thus, the correct option is A. If the lens is convex, the image cannot be virtual.
