Question

which way do convex lenses curve? they curve outwards. they do not curve and are flat. they curve inwards. a lens is a curved, transparent material that refracts light. a convex lens is a lens that curves outwards. as light passes through the lens, it slows down the light rays, bending them to meet at a focal point. this property is useful in optical devices like magnifying glasses and cameras.

Explanation:

A convex lens is a type of lens that is thicker in the middle than at the edges. By definition, convex lenses curve outwards. This curvature causes light rays passing through the lens to converge (come together). In contrast, concave lenses curve inwards, and flat lenses (like a window pane) do not curve at all.

Answer:

They curve outwards.
