Awave bending as it passes a point of land is an example of refraction. true or false

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
