A 3 cm tall object is placed at a distance of 7.5 cm from a convex mirror of focal length 6 cm. Find the location, size and nature of the image.

cm from the mirror on the side opposite to the object, 1.33 cm, virtual and erect

height of the object, h1= 3cm


The distance of the object from the mirror, u= 7.5cm


Since the object is placed beyond the mirror, the distance is taken as negative (sign convention)


Focal length of the mirror, f= 6cm



Using mirror formula,





Magnification m = -
