Question

When a concave mirror is used as a shaving mirror, where is the face of a man about the focus of the mirror? State the characteristics of the image seen.

Answer 1

Concave mirror:

1. A concave mirror's reflected surface is curved outward away from the source of light.
2. Concave mirrors reflect light inward to a focal focus point.
3. Unlike convex mirrors, a concave mirror's image changes depending on the distance between the item and the mirror.
4. When the face is placed close to a concave mirror (within the mirror's focal length), an enlarged and erect image of the face is produced, which can be utilized as a shaving mirror.

Between the pole and the focus is where the person's face is in relation to the mirror's focus. This creates an upright, magnified, and virtual image that is generated behind the mirror.

The following are the three features of the so-created image:

1. The images should be erect.
2. The images should be virtual.
3. The images should be magnified.

Therefore, it's simpler to shave smoothly when you can see an enlarged or magnified image of your face in the concave mirror.
