Solution
In an electric bulb, light is produced due to the glowing of the thin filament.
Explanation:
-
Inside an electric bulb, there is a thin wire filament, usually made of tungsten.
-
When electricity passes through this filament, it heats up due to resistance and begins to glow, producing light.
-
The glass case only protects the filament and may contain inert gases (like argon), but they do not produce light.
