Question

an object 5 cm is placed on the principal axis of a concave mirror of focal length 15 cm and object distance of 10cm find nature and position of image

Answer 1

hey..

when an object 5 cm is placed on the principal axis of a concave mirror of focal length 15 cm and object distance of 10cm then the image will be formed beyond the mirror. The image is virtual, erect and magnified

Answer 2

h=5 cm

u = 15 cm

f= 10 cm

by using mirror formula

1/v=1/f-1/u

1/v=1/-10 + 1/15

1/v=-3+2/30

v=-30

height of the image

h'/h=-v/u

h'/5=30/-15

h'=10 cm

position = 30 cm from concave mirror

nature = real and inverted

hope it help u
