It was approximately the shape of a pear with a sharp point on the center of the large end where the glassblower had left a tube thru which the air could be removed using a vacuum pump. After the air was removed this tube was heated again to cause it to seal the vacuum inside the bulb and the extra length cut off leaving the sharp point.
It did not take long before (for safety) this tube was moved to the narrow end, where it could be covered by the metal screw in base leaving the large end smooth. This is the way all modern incandescent bulbs are made, however the shape of the wide end now comes closer to spherical than pear shaped (although modern incandescent bulbs can be obtained in nearly any shape: flame, globe, retro, cylinder, etc.).

The condition of being misshappen or misrepresented on a map is called?
The condition of being misshapen or misrepresented on a map is called distortions. Distortion is the alteration of the original shape of something.
What are the formal elements?
The formal elements are Line, Form, colour/tone, Shape/pattern, texture, light and space......
How does a light bulb look inside?
the lightbulb looks like a pear-shaped glass with the turn piece at the top. But then it also depends on what type and size the lightbulb is. The energy efficient ones are swirly and they save energy.
If you look through the bottom of a glass beaker everything looks distorted why?
The glass at the bottom is not of uniform thickness and not of optical quality. The rays of light from the objects that you are looking at are, therefore diffracted and absorbed in different ways. This causes the distortions.
What are the uses of photochromic paint?
They are normally used for security markers or ultraviolet warning sensors. They can easily be mixed with base paint and used indoors for your own personal use.

What shape does an electric eel have?

What does reflecting a shape mean?
Reflecting a shape means creating a mirror image of the original shape by flipping it over a line called the reflection axis. This results in an image that is an exact copy of the original, but in the opposite direction. The reflection axis serves as the line of symmetry between the original shape and its reflection.
What e is something that can be stretche but goes back to its original shape?
Elastic can be stretched and then reverts back to its original shape.
What is the meaning of the word deformed?
out of shape, not original shape, out of posture
Will slime stretch an return to its original shape?
Yes, slime can stretch and return to its original shape due to its non-Newtonian properties. When applied force is removed, the slime will flow back into its original shape slowly.
What happens when you look into a spoon with light?
When you look into a spoon with light, you see a reflection of yourself or your surroundings. The curved shape of the spoon can distort the image, making it appear larger, smaller, or different than the original.
What material can return to their original shape after heating?
Shape memory alloys, such as Nitinol, can return to their original shape after being deformed when heated. These materials exhibit unique characteristics that allow them to "remember" their original shape and revert back to it upon heating.
Why is the filament wire of a bulb made very thin and given a helical shape?
The filament wire in a light bulb is made very thin to increase its resistance, which causes it to heat up and produce light efficiently when an electric current passes through it. The helical shape allows the wire to have a greater length within the bulb, maximizing the amount of light that can be produced.
