You should start with the lowest objective (10x) and work up to the highest or until the object is clear.
You should start focusing with the lowest magnification objective, typically the 4x objective. This allows you to locate and center your specimen before moving to higher magnifications.

It is important to start focusing with the lowest power objective because it provides a wider field of view and makes it easier to locate the specimen on the slide. Once the specimen is in focus at low power, you can then switch to higher power objectives for more detailed observation. Focusing at low power first also helps prevent the higher power objectives from coming into contact with the slide and potentially damaging the lens or specimen.
When using a microscope, always start with the lowest magnification objective and gradually increase the magnification to avoid damaging the slides. Additionally, remember to always use both hands when handling the microscope to ensure stability and prevent accidents.
To examine a prepared slide using a microscope, first place the slide on the stage and secure it with the stage clips. Start with the lowest magnification objective lens, adjust the focus using the coarse adjustment knob, then fine-tune the focus with the fine adjustment knob. Once the image is in focus, you can adjust the magnification by rotating the nosepiece to switch to a higher magnification lens for detailed observation.
start on the lowest objective
Movements viewed through the microscope are exaggerated quite a bit. As such, it's best to attempt to line up the object on the slide by looking at the slide directly, rather than through the objective.
Turning the coarse objective knob downward can cause the objective lens to come in contact with the slide, potentially damaging both the lens and the slide. It is best to always start with the coarse knob in the upward position to prevent any accidental collisions.
You should start by using the lowest power objective lens, usually the 4x or 10x objective, to locate and center the specimen on the slide. Once the specimen is in focus, you can switch to higher magnifications for more detailed viewing.
because it allows you to find the part of the slide you want to see, then you can zoom in by changing focus to see the frame in greater detail. if you don't start in low power it is extremely difficult to move around the slide

Before attempting to focus on an object on a slide, ensure the slide is centered, the objective lens with the lowest magnification is in place, and the stage is at its lowest position. Start by using coarse focus adjustment to bring the object into view, and then switch to fine focus to sharpen the image.
You should always start with setting a clear and specific goal or objective that you want to achieve. This helps to provide direction, focus efforts, and measure progress towards success.
b/c the high power only allows you to see a small portion of thee slide. where as the low power pretty much allows you to see the whole slide all at once.
You should start focusing with the lowest magnification objective, typically the 4x objective. This allows you to locate and center your specimen before moving to higher magnifications.
With a high power objective you see less sky and might not know where you are looking. With a low power objective you see more and it is possible to orient yourself among the objects in view.
Actually, it depends on the specimen which you are observing.. Suppose, if you are observing Tissues then you have to switch to 10X objective; but if you are observing mammalian cells or other cellular specimen then you have to switch to 45X objective...But, if you want to observe microbial cells then you have to put a drop a drop of paraffin oil on the smear made on the slide and then observe it into 100X oil immersion objectivelens...
