Low power objectives cover a wide field of view and they are useful for examining large specimens or surveying many smaller specimens. This objective is useful for aligning the microscope. The power for the low objective is 10X.
Do not touch lenses. ALWAYS start with the least magnification, and work upwards. Clean slides and microscope when finished with it. Cover microscope with dust cover when not in use. Never swing the microscope.
A light microscope
The ocular and objectives
The high-power objective on a microscope is larger lens with higher magnifying power. (40x)
Depends on the microscope, I would expect. All of the light microscopes I've ever used you could just turn to different objectives, but be careful not to crack the slide in doing so.
A "parfocal" microscope maintains its position as objectives are changed.

The magnification of the microscope depends on the objectives used. To calculate the total magnification, multiply the magnification of the eyepiece (10x) by the magnification of the objective lens being used. If you had two objectives, each with magnifications of, for example, 40x and 100x, the total magnification would be 400x and 1000x respectively when using the 10x eyepiece.

The focusing knobs are used to regulate the low power objectives on a microscope. These knobs help adjust the distance between the specimen and the objective lens to bring it into focus. By turning the focusing knobs, you can achieve a clear image when using low power objectives.
Lint-free cloth would be suitable.
