hey mate!!

Explanation:

u is distance of object from the mirror/lens

v is distance of image from mirror/lens

f is focal length of the mirror/lens

ho is object height

hi is image height

Sign is taken as – (negative) from pole of a spherical mirror towards object along the principal axis. This means sign is always taken as – (negative) in front of a spherical mirror.

f, the focal length, is positive for a concave mirror, and negative for a convex mirror. When the image distance is positive, the image is on the same side of the mirror as the object, and it is real and inverted. When the image distance is negative, the image is behind the mirror, so the image is virtual and upright.
