* Blackbody Radiation: Stars emit light across a wide spectrum of wavelengths, similar to a heated object. This is known as blackbody radiation.
* Wien's Displacement Law: This law states that the peak wavelength of the radiation emitted by a blackbody is inversely proportional to its temperature. In simpler terms, hotter objects emit more light at shorter wavelengths (blue end of the spectrum), while cooler objects emit more light at longer wavelengths (red end of the spectrum).
* Star Color: Stars, being hot objects, follow this principle. Blue stars are the hottest, with surface temperatures exceeding 25,000°C. Yellow stars like our Sun have surface temperatures around 5,500°C. Red stars are the coolest, with surface temperatures below 3,500°C.
Here's a breakdown of star color and corresponding temperature:
* Blue: Over 25,000°C
* Blue-White: 10,000°C to 25,000°C
* White: 7,500°C to 10,000°C
* Yellow-White: 6,000°C to 7,500°C
* Yellow: 5,000°C to 6,000°C
* Orange: 3,500°C to 5,000°C
* Red: Under 3,500°C
Important Note: While temperature is the primary factor, other factors like the star's composition and its distance from us can subtly influence its perceived color.
