pressure broadening वाक्य

उदाहरण वाक्य

1. Van der Waals forces are responsible for certain cases of pressure broadening ( van der Waals broadening ) of spectral lines and the formation of van der Waals molecules.
2. The gain bandwidth of the HeNe laser is dominated by Doppler broadening rather than pressure broadening due to the low gas pressure, and is thus quite narrow : only about 1.5 GHz full width for the 633 nm transition.
