Last updated on Feb 20, Planck's law describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T. As temperature increases, the peak of the curve shift towards a lower wavelength. The heat transfer coefficient or film coefficient , or film effectiveness is the proportionality constant between the heat flux and the thermodynamic driving force for the flow of heat i. The general definition of the heat transfer coefficient is:. It is used in calculating the heat transfer, typically by convection or phase transition between a fluid and a solid. As per the Wien's displacement law, the spectral distribution of the energy emitted at a given temperature has. Wien's displacement law is a principle in physics that states that the wavelength at which the intensity of radiation from a black body an idealized physical body that absorbs all incident electromagnetic radiation is at a maximum, and is inversely proportional to the temperature of the body. In terms of the spectral distribution of black body radiation, this means that there is a particular wavelength at which the emitted radiation reaches a peak, i. As the temperature of the black body increases, this peak emission shifts towards shorter wavelengths. So option 4 is correct. As temperature increases, the maximum shifts to shorter wavelengths, which is a direct consequence of the Wien's displacement law.
