Stokes' law  

Définition

  • 1) Fluid mechanics : At low velocities, the frictional force on a spherical body moving through a fluid at constant velocity is equal to 6πRηv, where R is the radius of the sphere, η the fluid viscosity, and v the velocity. 2) Spectroscopy : The wavelength of luminescence excited by radiation is always greater than that of the exciting radiation. (An Etymological Dictionary of Astronomy and Astrophysics, by M. Heydari-Malayeri, https://dictionary.obspm.fr/index.php?formSearchTextfield=stokes+law&formSubmit=Search&showAll=1)
