The focal length of a converging lens is 20cm. An object is 60cm from the lens. Where will be the image is formed. write the nature of the image

Answered by admin @



Focal length = distance between focus and centre of curvature =20cm
since ,2F=40cm
It is given that object is kept at 60 cm from centre of curvature
since object at beyond 2F


nature of object =Real and Inverted
size of object =smaller than the object
position of object= Between the F and 2F on the other side of lens
