Where can a man place his face to get an enlarged image when using a concave mirror to shave?

To get an enlarged image when using a concave mirror to shave, a man can place his face between the principal focus and the pole of the mirror. A concave mirror has a reflective surface that curves inward like the inside of a bowl. When an object is placed in front of a concave mirror, the mirror reflects light rays that converge and meet at a point called the "focal point" or "principal focus". The distance between the mirror and the focal point is called the "focal length". When a man places his face between the principal focus and the pole of the concave mirror, the mirror forms a virtual, upright, and enlarged image of his face behind the mirror. The image is larger than the actual size of his face because the mirror bends and converges the light rays in such a way that they create a magnified image. If the man places his face at the principal focus or beyond, the mirror will form a real and inverted image of his face, which will be smaller than the actual size of his face. Therefore, the correct answer is option (C) between the principal focus and the pole.
