After parallel rays of light pass through a _____ lens, they seem to come from a point. Experts can i plz get the answer with an explanation. Describe with a diagram if possible.

Refer to the ray diagram of parallel rays of light falling on a concave lens. The rays diverge when they pass through the lens. If you retrace the refracted rays backwards, they join back to the same point. Thus, they seem to originate from the same point.

Hence, the answer is concave lens.
