Question

Quizplus · Accepted Answer

Stars that are cooler than our Sun emit light that is more towards the red part of the spectrum, making them appear redder. This is due to Wien's displacement law, which states that the peak wavelength of radiation emitted by a star shifts to longer wavelengths (towards the red part of the spectrum) as the temperature decreases.
