The mirror and lens are likely to be concave.
Explanation:
It is given that, the focal length of spherical mirror and spherical lens have each a focal length of -10 cm. The focal length is the distance between the focal point and the optical center of the spherical minors or the lenses.
It is positive for the convex lens and the convex mirror. It is negative for the concave mirror and the concave lens.
So, in a spherical mirror and spherical lens have each a focal length of -10 cm. The mirror and lens are likely to be concave.
