Question

An object of size 1 cm is placed at a distance of 15 cm in front of a convex lens of focal length 10 cm. Find the nature, size and the location of the image

Answer 1

HEY MATE...

height of object=1 cm
object distance= -15 cm
focal length= 10 cm
image distance=?
height of image=?

LET'S FIND.....

1/f = 1/v-1/u
1/10=1/v-1/-15
1/v=1/10-1/15
1/v=1/30
v=30 cm

hence,image distance=30 cm

NOW,
m=-v/u= -height of image /h of object
i.e -30/-15=-v/1
30/15=-v/1
-v=2
i.e v= -2

hence, height of image = -2 cm

Since,the image formed is negative hence the image is real and inverted.
and the image is located at the right side of the lens.

HOPE IT HELPED.
