The image shows a diagram of a light bulb with labeled parts, but the labels are missing. The task is to identify and label the different parts of the light bulb based on their positions.
Let's go through each part step by step:
1.
Top left line – This points to the
glass bulb or
envelope, which is the outer glass covering that protects the internal components and contains the gas (usually argon or nitrogen) inside.
2.
Top right line – This points to the
inner glass envelope or
glass dome, which is the transparent cover that holds the filament and allows light to pass through.
3.
Middle left line – This points to the
support wires or
filament supports, which hold the filament in place within the bulb.
4.
Middle right line – This points to the
filament, the thin wire (usually made of tungsten) that heats up and produces light when electricity passes through it.
5.
Bottom middle line – This points to the
stem or
glass stem, which connects the filament to the base and helps insulate the electrical connections.
6.
Bottom left line – This points to the
metal base or
screw base, which is the threaded metal part that screws into the socket and conducts electricity to the bulb.
7.
Bottom right line – This points to the
contact point or
center contact, which is the small metal tip at the bottom of the bulb that makes electrical contact with the socket.

Final Answer:
Labeling the parts from top to bottom and left to right:
1.
Glass Bulb (Envelope)
2.
Inner Glass Envelope
3.
Support Wires
4.
Filament
5.
Stem (Glass Stem)
6.
Metal Base (Screw Base)
7.
Center Contact
These are the main parts of an incandescent light bulb. Each plays a role in allowing the bulb to produce light when connected to a power source.
