Answer 2

Parabolas can also be used to focus light. Flashlights and car headlights have parabola shaped mirrors behind them. Each beam of light that hits the parabola is reflected into the same focus point (as in the graphic above). This allows the light to be focused into one beam, instead of spreading out everywhere and being less effective.  It is said that Archimedes used this technique to burn enemy ships before they came to shore. He built a parabola of mirrors and used it to focus light on the ship, eventually causing it to catch on fire. This same technique has been used to cook and burn things.
