I learned today that the word laser stands for,Light Amplification by Stimulated Emission of Radiation...that means that they make light more intense by adding radiation to it in a special tube.
The book also said that Lasers have to go on in a single beam so to build a working Lightsaber would be impossible.
Sorry I haven't blogged lately I promise to write tomorrow. |
