Question

A convex mirror of focal length f produces an image half of the size of the object. What is the distance of the object from the mirror?

Answer 1

Use lens formula

Answer 2

1/v-1/u=1/f?
that one?

Answer 3

Object distance = -u
image distance = v
Height of image / height of object = v/u

Answer 4

hi/ho=-v/u

Answer 5

can u do it?

Answer 6

yeah

Answer 7

yeah as in can u post the sol.?

Answer 8

see now,
h / 2h = v/u
u = 2v

Answer 9

ok

Answer 10

\[1divv -1divu =1divf\]

Answer 11

\[1/v-1/u=1/f\]
