EM wave one wavelength is taken from the range Temperature T=\frac{0.29}{\lambda}

Radio

 100 cm 2.9\times 10^{-3}K

Microwave

 0.1cm 2.9 K

Infra-red

 100000ncm 2900K

Light

 50000 ncm 5800K

Ultraviolet

 100ncm 2.9\times10^{6}K

X-rays

 1 ncm 2.9\times10^8K

Gamma rays

 0.01 nm 2.9\times10^{10}K

 

These numbers indicate the temperature ranges required for obtaining radiations in different parts of the spectrum
