Explanation

When the object position is between F and pole of concave mirror, a magnified erect, and virtual mags is obtained.
When using a concave mirror to shave, a man can place his face closer to the mirror than the focal point of the mirror. By positioning his face between the focal point and the mirror, an enlarged image will be formed. The exact distance will depend on the specific mirror and the desired level of enlargement. It's important to note that concave mirrors can distort the image, so it's advisable to experiment with the distance to find the most suitable position for shaving.
