Question

draw a ray diagram in a case when covex lens is used as objective lens of a slide projector

Answer 1

Answer:

To use a convex lens as a magnifier, the object must be closer to the converging lens than its focal length. This is called a case 2 image. ... Ray 1 enters parallel to the axis and exits through the focal point on the opposite side, while ray 2 passes through the center of the lens without changing path.
