Peak blackbody wavelength calculator
WebThe λmax of the Sun is about 500 nm (5 x 10 -7 m). T = b / λmax T = 2.898 × 10 -3 / 5 x 10 -7 T = 5800 K So the Sun's surface temperature is about 5800 K. You can see from the formula that as the temperature increases, λmax will decrease. Stars of 12,000 K and hotter tend to have λmax at UV wavelengths. WebCalculation The total power radiated by a blackbody is given by the Stefan-Boltzmann equation, but it is often interesting to know the fraction of power which is emitted in the visible or some other wavelength range. Temperature T = K = °C Area A = cm 2 = x10^ m 2 Emissivity = (e = 1 for ideal radiator)

Webtouches at infinite wavelength. It also shows that the black body emits at a peak wavelength, at which most of the radiant energy is emitted. At 5000K the peak wavelength is about 5x10-7m (500nm) which is in the visible light region, in the yellow-green section. At each temperature the black body emits a standard amount of energy.

Webblackbody with surface temperature T=5800 K. The Sun's spectrum can be approximated by a blackbody spectrum. The peak wavelength for a 5800 K blackbody is at wavelength = 0.0029 / (5.8 x 103) m = (2.9/5.8) x 10-3-3m = 0.5 x 10-6m = 500 nm. The peak wavelength is for greenish-yellow light. WebThe wavelength at which maximum power is emitted can be calculated according to the equation λ max = 3 × 10 6 T where the wavelength is in nanometers (one billionth of a meter) and the temperature is in K (the constant 3 × 10 ^ 6 has units of nm × K ). This relationship is called Wien’s law.
