Radiation

Blackbody


How does the blackbody spectrum of the Sun work compared to visible light? Learn about the blackbody spectrum of the sun, a light bulb, a furnace, and the earth. Adjust the temperature to see the wavelength and intensity of the spectrum changes. See the color of the peak of the spectral curve.

Star radiation


The color of a star depends on its surface temperature and can be red, yellow, white, or blue. The higher the temperature, the bluer the star; the lower the temperature, the redder the star. Therefore, by observing the color of the star, its temperature can be deduced.
