What is the approximate surface temperature range for cool stars that radiate most intensely in redder wavelengths?
Answer
Around 3,000 Kelvin (K)
Stars with lower surface temperatures emit the majority of their light in the longer, redder parts of the visible spectrum. Specifically, stars exhibiting this cool characteristic have surface temperatures clustering around 3,000 Kelvin. As heating increases, the peak emission shifts towards shorter wavelengths; for instance, a piece of metal first glows dull red at lower temperatures before progressing toward yellow and eventually blue as the temperature rises significantly higher. This progression confirms that the 3,000 K range corresponds to the red and orange end of the stellar color spectrum.
