Question

If the image of an object formed by a concave mirror of focal length (f) is inverted and smaller than the object, then the object distance (u) is
u < 2f
u > 2f
u 2f
u = 2f

Answer 1

Answer:

u > 2f

Explanation:

u is larger than then image

Answer 2

u > 2f is the answer.

• 'u' refers to image distance and 'f' refers to focal length. Hence '2f' will be radius of curvature.

• Now, for a concave mirror, when an object is kept beyond the centre of curvature (i.e. u >2f) , the image produced is real, inverted and smaller than the object.

• Also, the real image is produced in between the focus and the centre of curvature (i.e. f < v < 2f).

• See the ray diagram for better understanding.
