Question

An object of size 6cm placed at a distance of 25cm in front of a concave mirror of focal length 15cm. Then find image distance nature and size of the image

Answer 1

Answer:

object of size=6cm

object placed at =25cm

focal length=15cm

MIRROR FORMULA=1/F=1/V+1/U

by applying sin convention

1/-15=1/v+1/-25

1/v=1/-15+1/25

1/v=-5+3/75

1/v=-2/75

1/v=-37.5

Magnification=-V/U

=-(-37.5)/-25

=-1.5

IMAGE SIZE=6×-1.5=-9cm

Nature of image is

REAL,INVERTED,ENLARGED.
