Planck's law · Wien's displacement
Controls
Every warm object glows with a Planck spectrum. Heat it up and the peak shifts to shorter (bluer) wavelengths — that's why stars range from red to blue-white.

Temperature5778 K
Peak wavelength502 nm
Colorwhite/yellow
Governing equation
Reading this result: At 5778 K the Planck curve peaks at 502 nm, inside the visible band — Wien's law makes peak wavelength ∝ 1/T, so doubling the temperature halves the peak wavelength and shifts the glow toward blue.
