Why the incandescent bulb with yellow color?
Answers
Explanation:
An incandescent bulb (classic) works by heating the tungsten filament. When you heat something, it will begin to glow, first in infrared we feel as heat, then in colors we see in the rainbow, starting with deep red, then orange, yellow, and white. Higher temperatures produce blues and ultraviolets, but by this time most metals are melted. Even with tungsten, one of the metals with the highest melting point, the temperature where it glows white, makes the metal very fragile. It breaks easily.
So, to make bulbs last longer, they make them so they burn at a lower temperature and glow with a yellow/white color.
Answer:
because those bulb glow by heating the tungsten wire and after getting heated it form reddish yellow light
also depend on the gas present inside the bulb
