Would the e14 have an advantage over the traditional light bulb?
E14 Light bulbs have an advantage over traditional light bulbs. They are designed using LED lights. These lights emit more light (making them brighter) and energy efficient capable of reducing your total energy costs when compared to traditional light bulbs.
Why do globes have a advantage over maps?
they give more physical traits and structuers.they give you a better idea of what the world is.
What does available light mean in photography?
It involves using the light that is available instead of over-riding or supplementing it with electronic flash.
Why do the electrons that orbit the nucleus of an atom never lose momentum?
electrons that orbit the nucleus of an atom never lose momentum because of the CENTREPETAL FORCE afford by the moving electron. In our Universe, when you get to things the size of an atom, the rules for how things operate changes from what we are used to. For starters, you can no longer say that an electron acutually HAS a momentum or even a position. Instead, you can only state (1) the probability that an electron has a specific momentum or position and (2) the AVERAGE momentum or position of an electron. And it is NOT the case that we lack the ability to measure these things, or that the electron "knows" these things but we don't -- the momentum and position of electrons are inherently UN-KNOWABLE, even to the electron itself! Thus, we can not say an electron "loses" its momentum over time, because we can't even say what its momentum IS. And we can't do so because the ELECTRON ITSELF doesn't "know" its own momentum! Confusing? Don't like this? Sorry -- that's how our Universe operates.
When spray painting do you spray the light or the dark color first?
Typically, you would want to lay down the lightest colors on the canvas and then paint over the light colors with a darker color. It looks better because if you did it the opposite direction, the darker colors would still show through the lighter colors to a degree.
What do electrons microscopes use to focus and magnify an image?
Electromagnets focus the electron beam on the specimen. This is a good advantage of electron microscopes over traditional light microscopes where lenses have to be used. Electromagnets can be used as electrons are charged particles and are deflected by magnetic fields.
What major advantage does a transmission electron microscope have over a compound light microscope?
The Compund light microscope allows people to view living cells. With the electron light microscope peole can only view dead cells but with very high detail. The electron microscope is also much more expensive than a compound ligh microscope. The compound light microscope is also much easier to transport from place to place, as the electron microscope is not.
What is one important advantage an optical microscope has over a more powerful electron microscope?
It is cheaper and used to observe larger objects. Electron microscopes look at much smaller things such as atoms.
What are the advantages of an electron microscope over a light microscope?
An electron microscope can reach a far greater magnifiction than a conventional microscope. It is obvious that the largest advantage of any type of microscope is to observe an organism that can not be seen by the unaided eye. Light microscopes are easy to use, can magnify up to 2000 times, enable magnification of live cells and their movement, and are relatively cheap compared to electron microscopes. The only disadvantage is that it can only magnify up to 1000 times, after that the image is blurry, whereas an electron microscope can magnify up to 100,000 times! However, electron microscopes are extremely expensive, difficult to use, and cannot observe live specimens.
Advantages of light microscope over elctron?
You mean "electron," of course. There are a number of "advantages," but this is really not the right way to look at it, so to speak. The most obvious one is color. Electron microscopes cannot detect color because they do not use light to illuminate the object, they use electrons. Depending upon what one is looking for, color contrasts can be very important. Electron microscopes have their own advantages, primarily much higher magnification.
What microscopes can enlarge images up to 100000 times or more?
An electron microscope can enlarge images up to 10,000,000 times (107x).Other types of microscopes that can achieve over 105 magnification include scanning probe microscopes, such as atomic force microscopes, electrostatic force microscopes, magnetic force microscopes, scanning tunneling microscopes, and piezo force microscopes.
One advantage of elcectron microscopes over light microscopes is their?
They have better resolution so the image they produce is more detailed and they can also be used to see internal details of cells. However the whole apparatus needs to be used in a vacuum so living organisms can't be observed.
Advantage and disadvantages of fluorescence microscope?
It is easier to view because it already has a light source. *Basically you can not use living tissue with Electron Microscopes, but only Light compound ones. "Because electron microscopes require a vacuum to operate samples must e preserved & dehydrated before they are placed inside the microscope. Meaning that living cells cannot be observed with electron microscopes, only with the light ones."

What scientist made over 500 simple microscopes?
The person who made over 500 microscopes was Anton van Leeuwenhoek.
What is an advantage of using an electron microscope?
Answer: Using an EM (electron microscope) you can look INSIDE a cell and take photos. This is different to an ordinary (or Light microscope) where you generally only see the outside of the cells - or at best can only see vague shapes inside the cell. Answer: The scanning electron microscope provides a number of advantages over an optical microscope. Primarily this centers around the fact that the wave lengths used are much smaller than the wavelengths of light. What you can see is, in par,t dependent on the relative size of the object and wavelength of the light you are using. For very small objects, like individual atoms, light just wont work. Secondly the electron microscope can be fitted out with equipment and analytical sensors to identify the atomic composition of materials in the field of view. These Scanning Electron Microscopes (SEM) are extremely useful in identifying trace contaminants. The standard microscope still has advantages. It can detect the polarizing capacity of organic compounds, it is cheap and easy to use, it can be used in the analysis of stained samples in microbiology, it can use transmitted light and reflected light to examine an object. A major advantage is that the surface of the viewed object does not have to be prepared by being covered with a very thin layer of metal to permit viewing.
How much magnification is needed to see a nanometer?
You cannot see down to the nanometer scale with light microscopes, you have to use something like a scanning tunneling microscope or an electron emission microscope. And since those don't use light I'm not sure you can really define the magnification.
