It means you have a good microscope.
You use the low power lens to find the specimen with a microscope. Once you have found the specimen on low power, you can switch to high power for greater magnification. Just be sure to use only the fine adjustment knobs for focusing on high power so the high power objective won't hit the slide.
A low magnification (e.g. 4x or 10x) would be most suited for scanning a slide to locate a specific object quickly. Once the object is located, you can then switch to a higher magnification for a closer examination.
So you can determine the actual size of what you are looking at.
What is the function of the light switch on a microscope?
fisrt,put the specimen into focus using a lower power lens, then switch to a higher power lens, if needed.
First put the specimen into focus using a low power lens, then switch to a higher power lens if needed.
If they are reasonably close together, you can use an "A/B Switch", otherwise you'll need to network them.
i think light two would turn on because it is in the middle of switch a and b
A failed switch is a common cause.
First put the specimen into focus using a low power lens, then switch to a higher power lens if needed.
The ground wire must remain connected to the box. The frame of the switch, and therefore also the screws, must remain connected to the box as well.
you probably have a bad headlight switch.
