Here is the correct matching of prisms and lenses with their purposes and uses:
-
Separates white light into different colors:: prism
-
Thicker at the center, causes light to bend inward, or converge:: convex lens
-
Surface curved like the inner surface of a sphere, causes light to bend outward, or diverge:: concave lens
-
Used in tools like telescopes and microscopes:: concave and convex lenses
This matching highlights the distinct functions and applications of each optical element.
