when an object is heated, explain the process how the light is emitted.

define the two terms, brightness and color.
explain them in relation to the wavelength(s) of light emitted. explain on what factors brightness depends, and on what factors color depends. thank u

Look up black body radiation. (hint)

anonymous · Answer

it is by the emission of photons due to deexcitation of electrons from the excited energy levels...

anonymous · Answer

correct, by it he means that when any object absorbs energy, at subatomic level -e gain energy and rise to a higher energy level than their own, so when these exited -e release this energy the energy is released in the form of light....!

anonymous · Answer

color of an object is, as seen by us the color (with particular wavelength) refracted or/and reflected by the object while the colors of other wavelengths get absorbed.....
while the brighteness of that color depends upon the Amplitude
