Black body wavelength temperature

WebHow does the blackbody spectrum of the sun compare to visible light? Learn about the blackbody spectrum of Sirius A, the sun, a light bulb, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum change. View the color of the peak of the spectral curve. WebAt the same time, the blackbody is also a complete radiator and can radiate electromagnetic waves of various wavelengths to the outside world. The blackbody model is an ideal model, which shows that there is a quantitative relationship between infrared radiation, wavelength and temperature.
