Question
In everyday life we know that something described as 'white hot' is hotter than something described as 'red hot'. What is the physics behind these everyday sayings?
a. The BB spectrum- Peak emission wavelength gets shorter as object gets hotter: Wavelength of white photons is shorter than red photons.
b. The BB spectrum- Peak emission wavelength gets longer as object gets hotter: Wavelength of white photons is longer than red photons.
c. The BB spectrum- Peak emission wavelength gets shorter as object gets hotter: White hot object is emitting all visible photons with roughly equal intensity. Red hot object is just emitting the long wavelength red photons.
d. The BB spectrum- Peak emission wavelength gets longer as object gets hotter: White hot object is emitting all visible photons with roughly equal intensity. Red hot object is just emitting the long wavelength red photons.
e. There is no physics behind these sayings
