As per the Wien's displacement law, the spectral distribution of the energy emitted at a given temperature has
1
a definite minimum and this minimum shifts to longer wavelengths as the temperature decreases
2
a definite minimum and this minimum shifts to shorter wavelengths as the temperature increases
3
a definite maximum and this maximum shifts to shorter wavelengths as the temperature decreases
4
a definite maximum and this maximum shifts to shorter wavelengths as the temperature increases
