Concave Mirrors: Uses |
|||||
Basically, they are used any time you want to make something’s reflection look bigger... they are magnifying mirrirs! In a shaving mirror or makeup mirror your reflection is larger so that you can perform 'personal grooming' to a high standard. Historical FootnoteIt has been said that Archimedes used a large array of mirrors to burn Roman ships during an attack on Syracuse . This has never been proved or disproved; however on a popular Discovery Channel show, MythBusters, a team tried to recreate the famous "Archimedes Death Ray". They were successful at starting a fire on a ship at 75 feet away, however, previous attempts to light the boat on fire using only the bronze mirrors available in Archimedes' time were unsuccessful, and the time taken to ignite the craft would have made its use impractical, resulting in the MythBusters team deciding that the myth was just a myth!
