о O Down 1. high-energy lightwaves that can cause problems when they reach Earth's surface 2 can't fins the definition to this, high-energy light waves that can cause problems when they reach earths surface? ​

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.
