concave mirror

Asked by  | 18th Feb, 2010, 07:14: AM

Expert Answer:

1/u + 1/v = 1/f        .........u - object distance, v - image distance, f - focal length.

1/v = 1/f - 1/u

= 1/15 - 1/10 = -5/150

v = - 30 cm

M = Magnification = -v/u = 30/10 = 3.

The image will be at a distance 30 cm, and 3 times the size of object and will be virtual, erect, since it's placed between the pole and focus of the mirror
