The current passing through the filament develops power (Watts = Amps * Volts). That power is dissapated in thermal energy (heat) and radiant energy (light).
The glowing part of an incandescent light bulb is the tungsten filament. When electricity passes through the filament, it heats up and emits light.
The energy that goes in is electrical energy; the energy that leaves it is visible light, as well as heat.
No, the glowing of a light bulb does not depend on frequency. Light bulbs glow because of the electrical current passing through the filament, causing it to heat up and emit light. The frequency of the electricity supplied to the bulb affects its brightness but not whether it will glow or not.
The bulb may not be glowing because it is burnt out, the power source is not connected, or the circuit may be broken. Check these aspects to troubleshoot the issue.
When a light bulb is glowing, electrical energy goes into the bulb and is converted into light and heat energy. The light energy leaves the bulb as visible light, while the heat energy is dissipated into the surrounding environment.
light.
No, the glowing of a light bulb is a reversible change because it can be turned off by disconnecting the power source. The light bulb will stop glowing once the electrical current is interrupted.

The place lights up
A light bulb is named due to it being a bulb-shaped glass object containing a glowing element.
The glowing of an electric bulb is a physical change. This is because the light produced is a result of energy being converted into electromagnetic radiation, without any change in the chemical composition of the bulb's components.

Electrical goes in. Electromagnetic (heat and light) come out.

Oxygen help the burning.
