an object 5 cm tall is placed 40 cm from a flat mirror find a) the distance from the object to the image, b) the height of the image, and c) the images magnification
Height of the object O = 5 cm
Distance of the object from the mirror u = 40 cm
(a). Distance of the image from the mirror v = u
= 40 cm
the distance from the object to the image = u + v
= 40 + 40
= 80 cm
b) the height of the image I = O
= 5 cm
c) the images magnification m = -I / O
= -1
