principle of microscopy includes 2 important aspects:
1. resolution and resolving power- the resolving power of a microscope is defined as the minimum distance by which 2 points must be separated in order for them to be perceived as 2 separate points rather than a fused image.
2. magnification- Linear (sometimes called lateral or transverse) magnification refers to the ratio of image length to object length measured in planes that are perpendicular to the optical axis. A negative value of linear magnification denotes an inverted image. Longitudinal
magnification denotes the factor by which an image increases in size, as measured along the optical axis.

ProfessorThe two basic principles involved in using a microscope are magnification, which enlarges the image of the specimen, and resolution, which refers to the clarity and detail of the image produced by the microscope. These principles work together to allow for better visualization of small objects or structures that are not visible to the naked eye.
In a simple microscope there is only 1 lens and 7 cm tall and there is a compound microscope where the image from objective lens is magnified again by the ocular lens used mainly for slides, in schools, labs, there are variations like brightfield illumination and darkfield illumination compound microscopes. Fluorescence microscope uses uv light and cells stained with fluorescent dyes. Confocal microscope uses fluorescence colors and laser light producing a 3d image. Scanning Acoustic microscope uses a computer and measures sound waves reflected back from object and it is used to study cells attached to a surface. Electron microscopes uses electrons instead of light and gives a greater resolution there are 3 kinds, TEM uses dead, ultrathin sliced specimens stained with heavy metal salt, SEM uses an electron gun that scans whole specimen and gives a 3d image and a Scanning-Probe microscope uses a metal probe to scan specimen and creates a 3d computer generated picture of specimen.

Why ribosome is unable to be seen using a ligt microscope?
ribosomes are not seen by using a light microscope bcz of its small size
Can the eukaryotic nucleus be seen with an light microscope?
The density of the nucleus can be seen using the light microscope, because the light microscope enlarges or makes the nucleus bigger.
To observe a small living organism a scientist might use a?
Microscope. A scientist might use a microscope. Well actually, it depends on the size of the animal. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically.
Which lens of a microscope is responsible for producing a magnified image on the inside of the microscope that is not seen directly by the person using the microscope?
The objective lens is responsible for producing a magnified image on the inside of the microscope. This image is then further magnified by the eyepiece lens before it reaches the eyes of the person using the microscope.
