What is role of He in this laser? Rami Arieli: “The Laser Adventure” The role of the Helium gas in He-Ne laser is to increase the efficiency of the lasing process. Two effects make Helium particularly valuable: The direct excitation of Neon gas is inefficient, but the direct excitation of He gas atoms is very […]
How do we map the sea floor today?
How do we map the sea floor today? Echo sounding is the key method scientists use to map the seafloor today.

What is a benefit to the alt az coordinate system?
What is a benefit to the alt az coordinate system? In addition to being easy to use, one of the main benefits of the Alt-Az coordinate system is that it is very useful in deciding when an object is well-placed for viewing, since one of the coordinates (altitude) describes the height of an object above […]

What do reverse faults create?
What do reverse faults create? (A) Reverse faults display severe damage in the form of landslides over the fault trace caused by the inability of the hanging wall to support the overhang caused by the fault displacement, folds, and compression features within the fractured hanging wall, and compressional block tilting. What effects do these faults […]
