Question

An object of height 12 cm is placed at a distance of 16 cm in front of a convex mirror of focal length 12 cm. Find the position of the image and length of the image ​

Answer 1

Explanation:

h = 5cm , u = -10cm , f = +10cm , v = ?? , m = ??

here , 1/f = 1/v + 1/u

so, 1/v = 1/f - 1/u = 1/10 - (1/-10) = 1/5 cm

so v = 5 cm

now,

m = -v / u = - 5/ -10 = 0.5

so image distance is 5 cm behind the mirror n the magnification is 0.5 .

Answer 2

Answer:

The image will be formed at a distance of 48 cm in front of the mirror.

The length of the image will be 36 cm.
