Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When looking at a specimen on your slide, you should always start with the
A
low objective lens
B
medium objective lens
C
high objective lens
D
super extra high power lens
Explanation: 

Detailed explanation-1: -Always start with the stage as low as possible and using scanning objective (4x).

Detailed explanation-2: -When using a light microscope it’s important to start with the low power objective lens as the field of view will be wider, increasing the number of cells you are able to see. This makes it easier to find what you’re looking for.

Detailed explanation-3: -Which Microscope Objective Should I Start With? Start Low! Since the 4x objective lens has the least magnification, but a larger field of view, it allows for more of the specimen to be seen, as well as locating the part of the sample you wish to view. This in turn makes it easier to focus on the sample.

Detailed explanation-4: -However, after the specimen is placed on the slide, starting with the low-power objective lens is essential to help position the specimen being observed. After using the low power objective lens, proceed to the medium power to help bring the specimen into a more precise focus.

Detailed explanation-5: -The statement is true. When using a microscope, you should always start with the lowest power objective when first viewing a specimen. Typically light microscopes have 4x, 10, 40x, and 100x objectives, therefore, you should start with the 4x objective.
