A 5 cm high object is placed 5 cm from a 20 cm focal length converging lens. determine the image distance, the magnification of the image, the image height and the properties of the image.​

Answer 1

Answer:

The Image is real inverted and magnified

Explanation:

Given:-

U=-5 cm

H1=5 cm

F = 20 cm

W.K.T

1÷f=1÷v-1÷u

1÷20=1÷v+1÷5

1÷v=-3÷20

V=-20÷3

W.K.T

M=v÷u=H2÷H1

H2=6.66 Approximately

M=H2÷H1=6.66÷5

=1.332
