Respuesta :
A hot tungsten filament emit electromagnetic radiation within the bulb because the tungsten is present within the bulb.
What temperature does a tungsten filament glow at?
Due to its high melting point, tungsten can be heated to 3000°C where it glows white hot providing very good brightness due to the presence of argon.
So we can conclude that a hot tungsten filament emit electromagnetic radiation within the bulb.

Electromagnetic radiation is made up of electromagnetic field waves. A hot tungsten filament emits electromagnetic radiation in the presence of Argon.
What is electromagnetic radiation?
Electromagnetic radiation is made up of electromagnetic field waves that travel through space carrying electromagnetic radiant energy. Radio waves, microwaves, infrared, light, ultraviolet, X-rays, and gamma rays are all examples of electromagnetic waves.
When tungsten is heated to a temperature of around 3000 °C, the tungsten starts to emit lights. Tungsten when used in a bulb as a filament then because of its high melting point when electricity is passed through it, it starts to shine white-hot and provides extremely good brightness due to the presence of argon.
Hence, A hot tungsten filament emits electromagnetic radiation in the presence of Argon.
