Question

an object 3.5 centimetre height placed at a distance of 8 cm from a convex mirror find the nature and the position of image also find the magnification. ​

Answer 1

u=−12cm

f=+8cm

ho=+3cm

Using mirror formula,

1/v +−301​  = 8/1

v/1​ = 60/3+2

v/1 = 60/5

= 12/1

v=+12cm

Therefore, the image will be formed at a distance of 12cm behind the mirror.

h,i =+0.4cm

Therefore, the image formed is diminished in size.
