The statement 'a distant star gives off a visible range of light whose color depends on its temperature' is supported by the wave model.
<h3>What is wavelength?</h3>
The wavelength can be defined as the periodic distance of a given wave that repeats in a constant way.
The emissivity of particles is a function of both wavelength and temperature of a given material/object. Visible wavelengths range from 700 nm to 400 nm (violet color).
Star temperature largely determines its color, blue stars are warmer than yellow and red stars, and red stars are cooler than yellow stars.
