The screw part or the part that holds it in place in many cases is a screw, so in that case it could be held up as an example of a screw. I doubt however if a light bulb with a bayonet fitting could be held as an example of a screw.
If it is a black and white negative, more light will pass through the lighter part. Since this is a reversal process, the light parts of the negative will be more exposed and produce a dark image.
The black part on the negative keeps light from reaching the photo paper.
Yes, a light bulb is matter.
what is a C. O. light bulb?
A light bulb can be part of a circuit.
"light bulb" is a noun.
If you place an end of a wire on the negative or positive side, put the outer metal part of the light bulb's cap on the other, and place the other end of the wire on the light bulb's cap's inner metal part, it will turn on.TipBefore you try to do this, always check that the voltage of the battery is equal to, or a bit less than, the voltage of the light bulb!Otherwise the light bulb may only give out a very bright flash and could easily be destroyed.

That part of a light bulb that causes light to light up is called the filament, and it is typically made from tungsten.
In an incandescent light bulb this is the filament. It is usually made of tungsten.
