The focal length of cancave mirror in case the object lies between pole and focus is positive or negative??( I got confused because the image is formed

behind the mirror and the focal length of cancave mirror for rest of the cases is negative so what about this case)


Focal length of concave mirror is always negative,regardless of object or image distance.

When the object is real focal length is negative but in the upper case image is behind the mirror so it is virtual and it's focal length will be positive.

it iiiis truth...... and real....
