No. It is believed that they illuminated their long tunnels with mirrors (or a series of them), or used flammable torches when appropriate.

Lewis Latimer did not improve the light bulb. He patented a more efficient way to produce carbon filaments for light bulbs, which helped make them longer-lasting and more affordable. Latimer's improvements were made in the late 19th century, specifically in 1881.
The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). In 1902 the Siemens company developed a tantalum lamp filament. From 1898 to around 1905 osmium was also used as a lamp filament. In 1906 the tungsten filament was introduced
A periscope makes use of the property of reflection to redirect light. Light enters one end of the periscope, reflects off mirrors inside the periscope, and then exits at the other end, allowing the viewer to see objects outside their direct line of sight.
A flashlight is a device whose purpose it to emit light, or be luminous. The 2 most common types of flashlights are LED or bulb. LED, or Light Emitting Diode flashlights run electricity though semiconductors that manipulate the current in a way that releases photons, the tiny packets of energy that make up light. Bulbs use incandescence to produce light, which is produced though the resistance of the material (or filament) to the electricity that is being forced though it. The material heats up, but due to the low oxygen in the glass bulb it cannot oxidize, and instead glows.
No, Albert Einstein did not make the first light bulb. The first practical incandescent light bulb was invented by Thomas Edison in 1879. Einstein made significant contributions to physics, but he did not invent the light bulb.
no Tomas Edison made the light bulb
first of all, you need a bulb, a wire, and ONE light bulb. You clip the wire on the battery and touch the wire on the bottom of the light bulb
in history, the first person to discover and make the first light bulb is Thomas Edison.
A light bulb can make heat and light.
Make a circuit with 2 wires a batery and a light bulb and touch wire to medle on light bulb
To install a light bulb into a light bulb receptacle, first make sure the power is turned off. Then, gently insert the base of the light bulb into the receptacle and twist it clockwise until it is securely in place. Finally, turn the power back on to test the light bulb.
Thomas Edison is widely credited with inventing the practical and commercially viable incandescent light bulb. He demonstrated the first successful light bulb in 1879 and his innovations helped make it a practical and widely used technology.
Thomas Edison developed the first commercially practical incandescent light bulb in 1879.
First all you have to do is paint a regular bulb black.
Electricity + Glass = Light bulb
argon is an element that make up a light bulb
