the law that the frequency of luminescence induced by radiation is usually less than the frequency of the radiation.The force acting downward is equal to 4/3πr3 (d1 - d2)g, in which d1 is the density of the sphere, d2 is the density of the liquid.
At a constant velocity of fall velocityis expressed by Stokes’s law as v = 2/9(d1 - d2)gr2/η.

A law stating that in fluorescence the wavelength of the emitted radiation is longer than that of the radiation causing it. This is not true in all cases.
