Answer:
If focal length is negative, it is a concave mirror while if it is positive, it is a convex mirror. So, the mirror having a focal length of -15 cm is a concave mirror.

Answer:
R = - 30
Nature → Virtual and Erect
Explanation:
→ Given, Focal length (f) = - 15
→ Radius of Curvature (R) = 2f
= 2 × (-15)
= - 30
→ Since, the sign is here is negative in the focal length
and Radius of Curvature.
→ Hence, the mirror is CONCAVE MIRROR.
→ Therefore, the nature is VIRTUAL AND ERECT.
