What happens when electrons travel through the filament of a light bulb
- A They escape from the filament, glowing brightly
- B They cause friction which heats the filament and emits light
- C They collide with fixed atoms in the filament causing them to vibrate, get hot and emit light
- D They carry heat from the battery to light the filament
That's Correct!
It's Wrong!
When electrons travel through the filament of a light bulb, they collide with fixed atoms in the filament. This collision causes the atoms to vibrate, which in turn generates heat. As the temperature of the filament increases, it starts to emit light, resulting in the glow of the light bulb. Therefore, the correct answer is that the electrons collide with fixed atoms in the filament, causing them to vibrate, get hot, and emit light.
