Question

What would you use to obtain a real and inverted image for any position of an object?
A. A convex mirror or a concave lens.
B. A concave mirror or a concave lens.
C. A concave mirror or a convex lens.
D. A convex mirror or a convex lens.

Answer 1

Hint: We know that a real image is formed when light rays converge at a point. A concave mirror also called a converging mirror and a convex lens also called a converging lens always forms a real image.

Complete Step-by-Step solution:
To get a real image light rays must be converging in nature whereas for a virtual image to form light rays should appear as diverging in nature. Real images can be captured on the screen and virtual images cannot be captured on the screen.
A convex lens is also known as a converging lens so it can be used to get a real image and to get an inverted image we need to place the object at a distance greater than the focal length of the convex lens as shown in figure 1.

Figure 1
A concave mirror is also known as a converging mirror so it can be used to get a real image and to get an inverted image we need to place the object at a distance greater than the focal length of the concave mirror as shown in figure 2.

Figure 2
In the above figures, we have shown the formation of the real and inverted image with the help of a convex lens and a concave mirror. So the correct option is C.

Note: For these types of questions, we need to know what is the nature of the image formed by a convex lens, concave lens, convex mirror, concave mirror, and plane mirror so that we can choose the mirror and lens accordingly. And for inverted always place the object away from the mirror at a distance greater than the focal length.
