Given below are some famous numbers associated with electromagnetic radiations in different contexts in physics. State the part of the electromagnetic spectrum to which each belongs.2.7 K [temperature associated with the isotropic radiation filling all space - thought to be a relic of the 'big - bang' origin of the universe]. |

Answer» Solution :Acording to Wien.s LAW, `lambda_(m)T=0.0029 mK`, `therefore lambda_(m)=(0.29cm K)/(2.7 K)=0.11 CM` We GET, `lambda_(m)~~ 11xx10^(-4)m` Radiation with above WAVELENGTH in the section of ..Microwaves.. of electromagnetic spectrum. |
