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

Solutions

Expert Solution

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
