doppler width meaning in Hindi

Examples

1. The second moment is called the Doppler width W.
2. The Doppler width basically is a measure of the width of the spectrum of the detected velocities.
3. Up-and downdrafts slow down the terminal fall velocities and can decrease or increase the Doppler width.
4. Since the air motion in the atmosphere affects the Doppler width, this parameter provides information about turbulence within the measured volume.
5. This causes an averaging over different Doppler states and results in an atomic linewidth that is much narrower than the Doppler width.
6. To be able to relate the change in skewness of the Doppler spectrum, the Doppler width should be cross-checked as well.
7. It shows the relation between the Doppler width W, depicted by the arrows, and the number of modes of the droplet size distribution.
8. These lasers need stability, rather than high power, requiring no more than the saturation intensity, but a linewidth much less than the Doppler width, usually several megahertz.
