The radiation energy density per unit wavelength at a temperature T has a maximum at a wavelength` lambda_(0)`. At temperature 2T, it will have a maximum wavelength

Electromagnetic radiation with maximum wavelength is

Power radiated by a black body at temperature T_(1) is P and it radiates maximum energy at a wavelength lambda_(1) . If the temperature of the black body is changed from T_(1) to T_(2) , itradiates maximum energy at a wavelength lambda_(1)//2 .The power radiated at T_(2) is

A star radiates maximum radiation at wavelength lamda_m at temperature T. What will be the temperture of another star which radiates maximum energy of wavelength 2lamda_m ?

A star radiates maximum radiation at wavelength lamda_m at temperature T. What will be the temperture of another star which radiates maximum energy of wavelength 2lamda_m ?

Eleactrons kept in an encloser at temperature T have a de-Broglie wavelength lambda . If the temperature of the encloser is increased, then the de Broglie wavelength of the electrons will
