1.	An object is 100 mm in front of a concave mirror which produces an upright image.What is the radius of curvature of the mirror and how.
Answer» The RADIUS of curvature of the MIRROR is greater than 200 mm. As per the question, the image formed is erect. In this case, the object is placed between pole and focus. Since the object distance is 100 mm, the focal length must be greater than 100 mm. Radius of curvature is twice the focal length. HENCE, radius of curvature must be greater than 200 mm. PO = 100 mm PF = f > 100 mm [∵ O LIES between P and F] PC = R = 2f > 200 mm

Answer»

The RADIUS of curvature of the MIRROR is greater than 200 mm.

As per the question, the image formed is erect.
In this case, the object is placed between pole and focus.
Since the object distance is 100 mm, the focal length must be greater than 100 mm.
Radius of curvature is twice the focal length. HENCE, radius of curvature must be greater than 200 mm.

PO = 100 mm

PF = f > 100 mm [∵ O LIES between P and F]

PC = R = 2f > 200 mm
