Solution:Stars emit light based on their temperature, following blackbody radiation principles.
The color you see corresponds to the peak wavelength of emitted light, which shifts with temperature.
| Star Colour | Approx.temperature (kelvin) | Example star |
|---|
| Blue | 10,000 – 40,000 K | Rigel |
| White | 7,500 – 10,000 K | Sirius |
| Yellow | 5,000 – 6,000 K | Sun (approx. 5,778 K) |
| Orange | 3,500 – 5,000 K | Arcturus |
| Red | 2,000 – 3,500 K | Betelgeuse |
Based on Wien’s Displacement Law,
Hotter objects emit light at shorter wavelengths (bluer light), while cooler ones emit at longer wavelengths (redder light).
