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
What else can I help you with?
What should you always remember when handling microscope slides?
Do not allow the high power objective to tough the lenses
Which objective should be in place both when beginning to use the microscope?
Scanning objective
A microscope should be stored with the objective in place?
Yes, it is recommended to store a microscope with the objective lens in place to prevent dust or debris from entering the lens threads and affecting the performance of the microscope. Additionally, storing the objective in place helps maintain the alignment and calibration of the microscope for accurate observations.
When viewing a specimen under the microscope you should always start with what?
When viewing a specimen under the microscope, you should always start with the lowest magnification objective lens. This allows you to locate and focus on the specimen before moving to higher magnifications for a closer look.
Why should you always begin to use a microscope with a lower power objective?
You should always begin using a microscope with a lower power objective to locate and focus on your specimen more easily. Low power objectives provide a wider field of view, making it simpler to find the area of interest. Additionally, starting with lower magnification minimizes the risk of crashing the objective lens into the slide, which can damage both the slide and the microscope. Once the specimen is in focus, you can then switch to a higher power objective for detailed observation.
When switching from the low-power objective to the high-power objective should you open or close the diaphragm Explain your answer?
When working with a microscope you should always take procauctions but one question I am asked a lot is When working with a microscope do you open or close the diaphram when working with the medium- and high-power objective nobs? The answer is you keep it open if you don't you won't be abler to see any thing.
Why should you look to the slide before you lower the objective of your microscope?
so the objective lens will not touch the slide.
When storing a microscope which objective lens should be pointed downward?
10x
What should objective lens should a microscope be stored in?
A microscope should be stored with the lowest-power objective lens in place to prevent damage to the higher-power lenses. It is recommended to keep the 4x or 10x objective lens in place for storage as they are less delicate than the higher magnification lenses.
When viewing a specimen under the microscope you should always start with the?
low power objective lens to locate and focus on the specimen before moving to higher magnifications.
Why should preliminary focusing always be done upwards?
When focusing the microscope downward, you take the chance of damaging the expensive objective lens by crushing the slide trying to get it.
What should always be in place both when beginning to focus and when replacing the microscope for storage?
When beginning to focus a microscope, the stage should always be at its lowest position, and the lowest power objective lens should be in place to prevent damage to the slide and lens. Additionally, ensure that the light source is appropriately adjusted for optimal illumination. When replacing the microscope for storage, remove any slides, lower the stage, and rotate the lowest power objective into position to protect the lenses and ensure safe handling. Finally, cover the microscope with a dust cover to keep it clean and dust-free.
