Question

difference between concave andcconvex lens

Answer 1

Convex lenses are thicker at the middle. ... Rays of light that pass through the lens are spread out (they diverge). A concave lens is a diverging lens. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus.

concave lens are thicker at the edges and thinner towards the centre
convex lens are thinner at the edges and thicker at the centre
