A Light bulb uses glass for the casing, brass/aluminium for the screw or bayonet mount, tungsten for the filament, copper alloy for connecting wires and porcelain for insulation.

Thomas Edison tested over 6,000 different materials for the filament of his light bulb before finding one that worked effectively.
For a simple experiment all you would need would be a working light bulb and a thermometer. You could also use a yardstick and measure how much heat there is at different distances from the bulb.

Thomas Edison and his team used a variety of tools and materials to invent the light bulb, including glassblowing equipment to create the bulb, vacuum pumps to remove air from the bulb, filaments made of different materials for testing, and various electrical equipment for conducting experiments and measurements. Additionally, they developed a carbonized bamboo filament that ultimately led to the successful creation of a long-lasting and practical incandescent light bulb.
When you want to use a MH bulb in an HPS ballast you must use a conversion bulb. It must be the same wattage as the HPS bulb
Argon must have a low reactivity to make it a suitable choice for use in a light bulb. As an inert noble gas, argon does not react with the tungsten filament or other materials inside the bulb, helping to prevent the oxidation and degradation of the filament at high temperatures. This property extends the lifespan of the light bulb and ensures consistent performance.
we use the light bulb in every day life
A 75 bulb will use more electricity.
No. The light bulb is two words, not a combination of light and bulb.
