The spectral series of hydrogen, on a logarithmic scale. The emission spectrum of atomic hydrogen has been divided into a number of spectral series, with wavelengths given by the Rydberg formula. These observed spectral lines are due to the electron making transitions between two energy levels in an atom.
Currently the state has 14,150 miles (22,770 km) of state-maintained roadways, including 1,233 miles (1,984 km) of Interstate Highways and 13,077 miles (21,045 km) of State Highways. [2] All of the U.S. Routes in Tennessee have a state route routed concurrently with them, though the state route is hidden and only signed along the green mile ...
The U.S. Highways in Tennessee are the segments of the United States Numbered Highway System that are maintained by the Tennessee Department of Transportation (TDOT) in the state of Tennessee. All of these highways in Tennessee have a state highway designation routed concurrently along them, though the state highway is hidden and only signed ...
Balmer noticed that a single wavelength had a relation to every line in the hydrogen spectrum that was in the visible light region. That wavelength was 364.506 82 nm . When any integer higher than 2 was squared and then divided by itself squared minus 4, then that number multiplied by 364.506 82 nm (see equation below) gave the wavelength of ...
The Tennessee state routes do not follow a systematic numbering system unlike the U.S. Highway System and some other states' highway systems. The routes are separated into primary and secondary routes though. Many of the routes are hidden in that they are overlaid on U.S. Routes and not signed.
Like the special U.S. routes, special state routes, as the name suggests, are typically marked with an auxiliary sign (or "banner") above (or occasionally below) the route shield, or a suffix letter after the number in the shield, except for the alternate routes.
State Route 46 (SR 46) is a north–south state highway located in Middle Tennessee. It mainly goes on a northwest to southeast course while passing through towns and cities such as Cumberland City , Dickson , Leipers Fork , along with mainly rural areas of Stewart , Houston , Dickson , Hickman and Williamson Counties .
U.S. Route 31 (US 31) is a part of the United States Numbered Highway System that runs from Spanish Fort, Alabama, to Mackinaw City, Michigan.In the U.S. state of Tennessee, it runs concurrently with Interstate 65 (I-65) for the first mile northward from the Tennessee state line.
