Detailed Solution

The above statement is true.
When a ray of light coming from infinity strikes the concave mirror, then it reflects back and passes through the focus of the mirror then it is a concave mirror. If an object is placed between the focus and the pole of the concave mirror, then the image produced will be a virtual and magnified image. That's why concave mirrors are used as shaving mirrors to get an enlarged image of the object.
