there is and its called an scanning tunneling.
==============
Sorry but this above answer is false there is NOT any instruments powerful enough to magnify atoms so that they can be seen. The model of an atom we have is a theory because we can't prove the way it looks. The Atom as we know it is just a theroy. Why would this be if we could see an atom. So again no there is NOT an instrument powerful enough to do this.
The instrument is an optical microscope.
True.
Bacteria is the smallest thing that can be seen using a microscope.
A microscope allows the human eye to examine tiny particles that otherwise cannot be seen.
The basic microscope is an optical instrument that uses a lens or a combination of lenses to produce magnified images of small objects, especially of objects too small to be seen by the unaided eye. Modern instruments, such as an electron microscope, use electronic or other processes to magnify objects in a similar way. Microscopes are used in industrial processes, in investigation of living cells, in comparative studies of chemistry and geology, and in diagnostic medicine.
Yes. They are too small to be seen with even the best optical microscopes.
They are to SMALL to be seen by any microscope!
Cell could be seen by using a powerful microscope...
If it is an optical microscope then the structures that can be see are those that are too small to be seen by the naked eye and larger than 1/2 a wavelength of light.
The Nucleus is seen through the use of an Optical Microscope and The Mitochondria is seen through an Electron Microscope.
The instrument is an optical microscope.
Atoms are too small to be seen with a standard optical microscope due to their size. Instead, advanced techniques such as scanning tunneling microscopy or atomic force microscopy are used to indirectly visualize atoms.
As viruses cannot be seen with the optical microscope, electron microscopes are used. All the "lenses" in an electron microscope are magnetic fields produced by electromagnets and/or electrostatic fields produced by electrically charged metal plates and/or rings.
Depends on the mechanism of the microscope, but with an optical microscope, anything smaller than 1/4 the wavelength of the light being used (around 10-6 Meters) eg a virus.
Cells yes, molecules for the most part no, atoms definitely not. A few extremely large molecules can be seen with light or electron microscopes (or even with the naked eye... technically, a flawless diamond is one large molecule), but normally something called a scanning tunneling microscope is used to image molecules and atoms.
Vacuoles and mitochondria are smaller than the resolution of an optical microscope (though with the right sort of dye some mitochondia can be seen as a small spot). They can be seen with an eletronic microscope.
Only the largest of viruses (e.g. Pox viruses) can be seen with a good light microscope (albeit with poor detail). Viruses usually can only be seen by electron microscopy. [2nd year Dental student, Naser]
