Final answer:
Convergence is exemplified by the meeting point of two rivers and the behavior of light rays passing through a converging lens, where they meet at a focal point. Convergent evolution in biology is another example, demonstrating similar trait development in unrelated species due to environmental pressures.
Step-by-step explanation:
An example of convergence is the meeting point of two rivers. This represents a physical coming together of two separate bodies of water, which is analogous to the way light rays converge when they pass through a converging lens.
Converging lenses cause parallel light rays to meet at a focal point as they pass through the lens, which is clearly demonstrated by the property that a ray entering a converging lens parallel to the optical axis will pass through the focal point on the other side of the lens.
Additionally, convergence in biological systems is illustrated by convergent evolution, where unrelated species develop similar traits independently, often as a response to similar environmental pressures or challenges.A converging lens is an example of convergence.
When light rays enter a converging lens parallel to its axis, they converge at a focal point on the other side of the lens. This convergence of light rays is a demonstration of convergence.
