WebA particular blackbody has a radiation spectrum that peaks at a wavelength of 660 nm. Part (a) What is the temperature of the blackbody in units of Kelvin? Part (b) If the temperature of a blackbody is 4300 K, at what wavelength, in units of … WebFormally, Wien's displacement law states that the spectral radiance of black-body radiation per unit wavelength, peaks at the wavelength λpeak given by: where T is the absolute …
Answered: Our sun
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.

Blackbody Radiation - GSU
WebIn simple terms a blackbody is a volume which operates as a perfect absorber and emitter of thermal radiation. More specifically a blackbody is a volume which: Absorbs all incident radiation independent of wavelength and direction. Will emit more energy than any other surface at a given temperature. Emits radiation independent of direction, i.e ... WebA higher temperature will lead the wavelength of peak emission to be at a shorter wavelength. ... The surface of the Earth and the sun act like blackbodies.A blackbody is an object that takes in and gives off all possible radiation with 100% efficiency.The following two laws—Stefan-Boltzmann and Wein's laws—can be used to explain the ...
