Question

i need examples of a concave and convex lens. Also how could i use absorb {to take i heat} in a science story?

Answer 1

A concave lens curves in

A convex lens cuves out

You are going to have to rewrite that second question.

Answer 2

Alrighty...one example of a convex lens is a magnifying glass.  Concave lenses are used to correct myopia, or nearsightedness.  One use of the word absorb would be a lizard sunning itself on a rock, as it is absorbing infrared radiation (heat) from the sun.
