what happen if converging rays are made to pass to a convex lens?
what happen if divergent rays are made to pass to a concave lens?

A converging lens is thicker in the middle and thinner at the edges, causing light rays to converge towards a focal point. A diverging lens is thinner in the middle and thicker at the edges, causing light rays to diverge away from a focal point.
No, a lens can only be either converging or diverging. The shape and curvature of the lens determine its properties and cannot be changed.
In rare situations, such as in high-index materials or extreme temperatures, the refractive index of the lens may change, causing a converging lens to behave like a diverging lens and vice versa. This is known as anomalous refraction.
Generally, a thicker lens will have a shorter focal length, while a thinner lens will have a longer focal length. However, this relationship may vary depending on the shape and curvature of the lens.
Yes, a lens can have multiple focal points depending on its shape and curvature. For example, a biconvex lens can have two focal points, one on each side, while a plano-concave lens can have a virtual focal point.
