Web12 Apr 2024 · Figure 5a shows the wavelength responses when the temperature increased or decreased, and the relationship between the peak wavelength and temperature is shown in Figure 5b with R-squared of the fitting curve of 0.9999. By means of data fitting, the regression equation can be expressed as: Web28 Dec 2024 · Suppose the peak wavelength of the star is λmax = 340 nm: Convert the wavelength to meters: λmax = 3.4×10⁻⁷ m. Divide the Wien's displacement constant by this value: b / λmax = 2.8977719×10⁻³ m·K / 3.4×10⁻⁷ m. The resulting temperature is about … This Stefan Boltzmann law calculator describes the power radiated from a …
