Question

An object is placed at 12cm from a convex mirror of R=12cm find the position of image.

Answer 1

Answer:

according to mirror formula

if

v =image distance

u=object distance

f=focul length

1/v + 1/u =1/f

1/v = 1/f -1/u

= 1/6 - (-1/12)

= 1/6 + 1/12

= 2/12 + 1/12

= 3/12

= 1/4

v = 4

ans. 4 cm behind the mirror
