If the average energy of thermal neutrons is measured in terms of temperature through the law of equipartition of energy, like gas molecules, determine the wavelength of thermal neutrons at room temperature of `27^(@)C`.
(Given, `h=6.627xx10^(-34)J-s`, Boltzmann.s constant, `K=1.38xx10^(-23)J" molecules"^(-1) K^(-1)and"mass",m=1.67xx10^(-27)"kg"`)

Answer

`1.455Å`
