A 100W bulb emits light uniformly in all directions. A metallic sodium surface is kept at a distance of 1m from the bulb. If all the energy emitted is absorbed by the top layer of the surface and all the energy given by a sodium atom is taken by one electron , find the time needed by an electron in a sodium atom to receive an energy of 1eV(The size of sodium atom= 1A)
