Question

Quizplus · Accepted Answer

The wavelength of light is much shorter than the wavelength of infrared waves. As the temperature of an object increases, its wavelength shifts towards the shorter wavelengths. Therefore, for an object to emit light waves rather than infrared waves, its temperature would have to be higher.
