WebIn any case, it's only half true that a lens can concentrate sunlight to a point that might then be used to a start a fire. Only a converging lens will do that — a lens that converges parallel rays of light down to a point. Some lenses do just the opposite — they diverge parallel rays of light from a point. WebWhen you focus the sun's rays using a magnifying glass (or in this case sphere of water) you can increase the intensity roughly ten thousand fold. This increases the temperature of wood to its...
