i think its theory but im not to sure
<span>The
surface of a mirror is smoothly and therefore the rays of light are
reflected with the same angle they hit the surface. The surface of a
piece of wood on the other hand has a lot of microscopical
imperfections and hence the rays of light are reflected in multiple
directions.</span>
What exactly is the question you are asking?
Many, many substances ... when they are surrounded by air and get very
hot ... they combine with the oxygen in the air, forming new substances.
The process is called "burning", and the new substances are often called
"ashes".
If the tungsten filament [were] surrounded by air, then when you turned on
the light and the filament got hot, it would burn, turn to ash, and fall to the
bottom of the bulb in a little pile of dust. This would all happen so fast that
you would see a short, bright '<em>flash</em>', then the light would go out forever, and
you would say "OH ! The bulb burned out. We need to go to the store and
buy another one."
