Asked in Scientific Method
What makes lasers of different colors?
Different wavelengths of light. The color doesn't matter much to the strength --- it's, for example, the size (amount of light emitting material that matters), and other attributes of the laser that matter. One can change the color by using different materials for generating the light. A helium-neon laser generates the familiar red laser light, other materials can generate green laser light, etc. ...

Asked in Science
What are the other uses of krypton?
Krypton, like the other noble gases, can be used in lighting and photography. Krypton light has a large number of spectral lines, and krypton's high light output in plazmas allows it to play an important role in many high-powered gas lasers, which pick out one of the many spectral lines to amplify. There is also a specific krypton fluoride lasers. ...

Asked in Physics, Chemistry, Elements and Compounds
Do elements make up everything?
No. An element is a group of the same kind of atoms. Compounds and mixtures contain different kinds of atoms, and thus, different kinds of elements. However, there are several things that are not made up of atoms. This includes light, different kinds energy, neutron stars, black holes... and the mysterious dark matter. The Universe contains at least 5 times as much dark matter, than atoms and other kinds of known matter. ...
