Answer 1

Answer:position=-16cm

Nature=real and inverted

Size=-12cm

Answer 2

Explanation:

Here we have given that,

h=6cm

u=-8cm

f=-16cm

h'=?

v=?

now,according to mirror formula

1/f=1/u+1/v

1/v=1/f-1/u

1/v=1/-16--1/-8

1/v=1/8-1/16

1/v=2-1/16

1/v=1/16

v=16cm

and according to magnification formula

h'/h=-v/u

h'=-hv/u

h'=-6×16/-8

h'=12cm

The image is enlarged,errect,virtual.
