Question

a) Draw a ray diagram to show the formation of image by a convex lens when an object is placed in front of the lens between its optical centre and principal focus.

b) In the above ray diagram mark the object-distance(u) and the image-distance(v) and state how these distances are related to the focal length (f) of the convex lens in this case.​

Answer 1

Answer:

M = v/u

1 _ 1 = 1

v. u. f

This is the answer
