This discussion has raised in my mind the following question that has
occured to me before.
The surface of the Sun is about 5800 K and emits spectrum of light that
has a yellow cast. The filment of a light bulb, if made of tungsten,
could not be hotter than 3695 K, its melting point, and yet emits light
that appears white, even in the small clear bulbs used to demonstrate
series and parallel circuits. The white light should indicate that the
tungsten is at a higher temperature than the surface of the Sun. What am
I missing here?
