Question

Bose-Einstein condensation has the inner energy of the atoms droping and falling into the same quantum mechanical state. Cesium is used where it has a spectral transition at 800 nm, that is, if cesium atoms are in an excited state and fall to the ground state they emit IR light of 800 nm wavelength. An irradiance of 1.8 nW / cm2 is measured from the position of a dot where light(cesium atoms) is emitted from, which is positioned 1.0 dm behind it.

State the equations for the electric and magnetic field if one would think of a distance greater than 1.0 dm.

Answer 1

in this equation c= constant whereas in other equation 'c' represents speed of light. Please go through the solution given in attached image
