Question

the focal length of a converging lens is 20cm 2cm height object is 60cm from the lens where Will be the image be formed and find the height of the image​

Answer 1

Converging lens means convex lens

Focal length; f a convex lens is positive

F=20cm

U=-60cm

Ho=2cm

I/20=1/v-1/-60

1/20=1/v+1/60

1/20-1/60=1/v

40/1200=1/v

V=30cm

m=v/u=hi/ho

m=30/-60=hi/2

2×1/-2=hi

hi=-1cm

I hope this helps ( ╹▽╹ )
