What is macroscopic electric field?
As far as I understand, the macroscopic field (E) is the average field experienced by the whole material, whereas local field (E local) is the field experienced by an atom of interest.
What is macroscopic physics and microscopic physics?
The macroscopic world contains the things we can see with our eyes. The microscopic world contains the building blocks of matter, the atoms and molecules. Mesoscopic physics addresses fundamental physical problems which occur when a macroscopic object is miniaturized.
What is local electric field?
Local electric field at an atom In dielectric solids, the atoms or molecules experience not only the external applied electric field but also the electric field produced by the dipoles. The resultant electric field acting on the atoms or molecules of dielectric substance is called the local field or an internal field.
What is microscopic field?
Definitions of microscopic field. the areas that is visible through a microscope. type of: field, field of view. the area that is visible (as through an optical instrument)
What is meant by macroscopic and microscopic?
Macroscopic things are large enough to be seen without using a microscope. Macroscopic is the opposite of microscopic, which describes anything you need a microscope to see.
What is difference between mesoscopic and microscopic?
As adjectives the difference between microscopic and mesoscopic. is that microscopic is of, or relating to microscopes or microscopy; microscopal while mesoscopic is on a scale between microscopic and macroscopic.
What is external and internal electric field?
(a) (E int,0 , B int,0 ) are the fields produced by the internal sources, i.e., the charges and currents constituting the material sample (without the external perturbation). (b) The external fields are produced by the external sources in the absence of the medium.
What is meant by local field in a dielectric and how is it calculated for a cubic structure?
Local field: When a liquid or solid dielectric placed in an external electric field , it’s atoms becomes electric dipole which provides field which is different than applied field. the total field at the atomic sites is called the internal field or local field. It is represented by Ei or EL. E(local field)=E+p/3€
What are the 5 different types of microscopes?
5 Different Types of Microscopes:
- Stereo Microscope.
- Compound Microscope.
- Inverted Microscope.
- Metallurgical Microscope.
- Polarizing Microscope.
What is microscope specimen?
Specimen or slide: The specimen is the object being examined. Most specimens are mounted on slides, flat rectangles of thin glass. The specimen is placed on the glass and a cover slip is placed over the specimen. This allows the slide to be easily inserted or removed from the microscope.
What are examples of microscopic?
Size. Bacteria are the smallest micro-organisms, ranging from between 0.0001 mm and 0.001 mm in size. Phytoplankton and protozoa range from about 0.001 mm to about 0.25 mm. The naked eye can see only the largest phytoplankton and protozoa.
What is the macroscopic electric field of a sphere?
The macroscopic electric field at the field point P@ r G inside the sphere consists of two parts: – A contribution from the average electric field Erout( ) GG due to electric charges outside / external to a small imaginary sphere (of radius δ\) centered on the point P, and: – A contribution from the average electric field Erin( )
What is the macroscopic E-field?
Hence the macroscopic (i.e. microscopically averaged- over) E-field can be seen as being truly electrostatic, for so-called time-independent situations. Suppose we want to calculate the macroscopic electric field Er( ) GG at some point, r G inside a solid dielectric sphere of radius, R as shown in the figure below.
What is the difference between macroscopic and microscopic?
The terms macroscopic and microscopic refers to two different scales that are useful in determining the size of different compounds. Macroscopic substances are large enough to be seen by the naked eye without any magnifying instrument.
What do you mean by microscopic substances?
The term microscopic refers to substances that are very small, therefore, we cannot observe them without a magnifying device. Therefore, we need to use optical instruments such as magnifying lenses, light microscope, electron microscope, etc. in order to observe these substances.
