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.
One principle of operating a microscope is that there is more than one lens that can be used. Another principle of operating a microscope is that items to be looked at should be in a saline solution to help see them more clearly.
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.

The two basic principles that are involved in using a microscope are magnification and observation. There are different types of microscopes which mainly include optical and electron.
1. At least two adjustable lenses
2. A light source to see the image
The two basic principles for using a microscope would make sure its on and slide is in place. Focusing in on the area of the slide using the large knob then the smaller knob.
The two basic principles that are involved using the microscope are magnification and observation. They are both done by examining an object through the lens of the microscope.
Basic technique in microscopy makes use of the differences in refractive index of cell structures.

ribosomes are not seen by using a light microscope bcz of its small size
All. All skills of using a microscope assisst in being able to use a microscope properlly.
Antonie van Leeuwenhoek has been credited with discovering protozoa using a microscope.
A simple version of a compound microscope was used to discover cells. Robert Hooke first described cells in 1665, using a compound microscope. Soon after, Anton van Leeuwenhoek also studied cells using a microscope with more advanced lenses.
The two basic principles that are involved using the microscope are magnification and observation. They are both done by examining an object through the lens of the microscope.
The basic requirement for you to see an object using the microscope is light. The amount of light will determine the visibility of the specimen.

It depends on what kind of microscope you're using.
The function of the base of the microscope is to provide support to the microscope. The base is important when one is using the microscope or carrying it.
The two behavioral principles involved in differential reinforcement are reinforcement, which involves providing a reward for a specific behavior to increase the likelihood of it occurring again, and extinction, which involves withholding reinforcement for an undesired behavior to decrease its occurrence. By using these principles together, individuals can be encouraged to engage in desired behaviors while reducing undesirable behaviors.
