Detailed Solution

Since, the concave mirror forms a virtual, erect but magnified image of the object when the object is placed at a distance smaller than focal length of mirror. So dentists use concave mirror to examine small cavity.

Concave mirror will form a diminished image if the object is placed away from the center of curvature.

So, Statement 1 is true, statement 2 is false.
