40-50x
When using a 4x objective lens on a microscope, the total magnification is calculated by multiplying the objective lens magnification by the eyepiece magnification. If the eyepiece (ocular) lens is typically 10x, the total magnification would be 4x (objective) × 10x (eyepiece) = 40x. Therefore, when scanning with a 4x objective, the total magnification will be 40x.
The total magnification with the scanning lens on a microscope typically ranges from 4x to 10x. This is because the scanning lens typically has a magnification power of 4x or 10x, and when combined with the magnification of the eyepiece (usually 10x), the total magnification ranges from 40x to 100x.
The medium power scanning objective in a microscope typically has a magnification of around 20x to 40x. It is used to locate and focus on the specimen at a lower magnification before switching to higher magnification objectives for detailed observation.

The scanning power objective relates to the objective lens. Most microscopes provide two or more objective lenses to give a choice of magnification power. Some also include an oil immersion lens for even greater magnification.
The smallest magnification lens on a compound light microscope is the scanning objective lens, typically with a magnification of 4x.
The shortest objective on a microscope is typically the scanning objective, which has the lowest magnification power (usually around 4x). This objective is used to locate and focus on the specimen before switching to higher magnification objectives for detailed viewing.
The magnification of the objective lens is 10x. The magnification of the scanning lens is 4x. Therefore if you are viewing an object under scanning power, the total magnification is 40x.
The oil immersion objective lens provides the highest magnification in a compound light microscope, typically ranging from 90x to 100x. This lens requires a drop of oil to be placed on the slide to reduce light refraction and increase image clarity and magnification.
In a light microscope magnification is varied by using different lenses to refract the light. In an electron microscope magnification is varied by altering the configurations of magnetic fields to bend the electron beam.
The lower objective on a microscope helps to provide initial magnification of the specimen. It typically has a lower magnification power compared to the higher objectives. This objective is usually used for scanning the specimen and locating areas of interest before moving to higher magnifications.
The scanning objective is used to quickly locate and focus on the specimen before switching to higher magnification objectives for detailed imaging. It typically has a low magnification (4x-10x) and a wide field of view to facilitate navigation and initial observations of the sample.
