The low power objective is used first for two reasons: First, focusing the low power objective will insure that the other objectives will be at the proper height. Smashing a slide with an objective can damage the objective. Second, you can see a greater area with the low powered objective. This allows you to easily locate an object of interest, center it in frame and then zoom in on it.
LPO (Low Power Objective) provides a wider field of view and lower magnification, making it suitable for locating objects and observing their overall structure. On the other hand, the higher magnification and narrower field of view of the HPO (High Power Objective) allow for more detailed examination of specific features or structures of the specimen. The scanner objective provides the lowest magnification and widest field of view for easily locating and navigating around the specimen on the slide.
Under a low power objective, the letter "e" would appear larger and more defined compared to a higher magnification. It may appear clearer and easier to discern the details of the letter.
The image becomes inverted under the low power objective due to the design of the microscope and the way light rays are refracted and magnified by the lenses. The inverted image is a result of the optics in the microscope system.
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
You can estimate the size of the object by comparing the field diameters observed under the low power objective lens (4x) and high power objective lens (40x). Calculate the ratio of the field diameters (40x/4x = 10), and use this ratio to estimate the size of the object viewed under the high power objective lens. Simply multiply the size of the object viewed under the low power objective lens by the ratio (field diameter at 4x) to get an estimation.
Low power objective is like our eye if we want to see we can just see normally but if we want to see something very small but want to see properly at that particular part then we always go for some lens of something powerful. That's the same thing when we want to know something deeply we go for high power microscope to read a more detailed study of a particular part of object under the microscope.
When an objective lens in a light-path objective (LPO) microscope is shifted from the Low Power Objective (LPO) to the High Power Objective (HPO), the image becomes magnified and the field of view decreases. This results in higher magnification but a smaller area of the specimen being visible at once.

first view with low power then gradually increase the power. hope it helped you!
The coarse adjustment knob moves the objective a lot while the fine adjustment knob moves it just a little, so using the coarse knob under high power can cause the objective to hit the slide and potentially damage the slide or the objective. The fine adjustment knob provides more precise control for focusing under high power, allowing for better clarity and accuracy.
