Question

3. An object of size 7.0 cm in placed at 27 cm in front of a concave mirror of focal
length 15 cm. Find the position and nature of image.​

Answer 1

Answer:

HEY MATE HERE IS UR ANSWER:-

Object height (h) =7cm

Object distance (u) =-27cm

Focal lenght of the concave mirror (f) =-18cm

Using mirror Formula, 1/f=1/v+1/u

we get, 1/v=1/f-1/u

1/v=(1/-18)-(1/-27)

=-1/18+1/27

= -3+2/54

1/v =-1/54

v=-54cm

by using m= h/h'= -v/u

7/h'=-(-54)/(-27)

h'=-7x(-54)/(-27)

h' =-14cm

Since h>h' the image is enlarged. As the value of h is negative, the image is inverter.

Since v is negative, the image formed is real.
