Question

An object is placed at a distance of 8cm in front of a concave mirror of focal length 16cm, calculated the position of the image.

Answer 1

object distance u= 8 cm

focal length f = 16 cm

image distance v= ?

mirror formula 1/u+1/v=1/f

1/v=(1/f)-(1/u)

= 1/16–1/8

= (1-2)/16

1/v=-1/16

v=-16 cm
