Draw ray diagrams showing the image formation by a convex lens when an object is placed

(a) between the optical centre and focus of the lens

(b) between focus and twice the focal length of the lens

(c) at twice the focal length of the lens

(d) at infinity

(e) at the focus of the lens

Answers (1)

Explanation:-

A convex lens is a converging lens that brings parallel rays of light to a point called the focus. The behavior of the image formed by a convex lens depends on the position of the object relative to the lens's optical center (O) and focal length (F). The position of the object affects the size, nature (real or virtual), and orientation of the image.

(a) between the optical center and focus of the lens

(b) between focus and twice the focal length of the lens

(c) at twice the focal length of the lens

(d) at infinity

(e) At the focus of the lens
