The focal length of a converging lens is $20 c m$ . An object is $60 c m$ from the lens. Where will the image be formed and what kind of image is it?

Solution

Focal length = distance between focus and center of curvature $= 20$ cm
Since $2 F = 40$ cm
It is given that object is kept at $60$ cm from center of curvature since object is beyond $2 F$ .
Nature of image $\to$ Real and inverted
Size of image $\to$ Smaller
Position $\to$ Between $F$ and $2 F$ on other side of lens.
