WebNow we define the common nomenclature used in geometrical optics. For the convex lens seen in the image below, we see the parameters d o, d i, and f.All of these are lengths … WebFirstly, because the concave lens diverges a straight beam of light whereas the convex one converges a stream beam of light. Further, convex has a thicker lens and it gets thinner as we move towards the edges. However, the concave lens is thinner at the centre and keeps getting thicker as we move towards the edges.
