Why it is easier to find the focal point of a convex lens than that of a concave lens?

It is easier to find the focal point of a convex lens than that of a concave lens because a convex lens has a positive focal length, meaning the focal point is on the opposite side of the lens from the incoming light. In contrast, a concave lens has a negative focal length, making it more complex to determine the exact location of the focal point. Additionally, the shape of a convex lens converges light rays to a single point, simplifying the process of identifying the focal point compared to the diverging nature of a concave lens.
