If you mean magnification, unless you have a confocal microscope, the objective lens with the lowest mag will be the shortest -- largest clearance between the bottom of the lens and the stage. You can easily load and unload (slide in or out) the sample off the stage. If the reason is the above, I have a better way. I always load the sample with the lens rotated away -- the best clearance will be when no lenses are in position. If so, I would have lowered the stage quite a bit so that when I swing the lens in position, I am not scratching the sample.
However, a better reason for starting with low mag would be that you can focus much easier with the lowest-mag lens and then refocus to go to a higher mag -- the sample is approximately in focus all these times. When the sample is way out of focus, as when the highest-mag lens is on when you first insert the sample, it is hard to know which direction to turn the focus knob without scratching the sample.
Surface microscopes offer several advantages over other types of microscopes for analyzing samples. One key advantage is their ability to provide high-resolution images of the surface of a sample without the need for complex sample preparation. This allows for quick and easy analysis of samples in their natural state, making surface microscopes ideal for studying surface features and textures. Additionally, surface microscopes are often more user-friendly and cost-effective compared to other types of microscopes, making them a practical choice for researchers and scientists.
ComEd, like many utility companies, may not have the capacity to generate enough power to meet peak demand periods. In those cases, they may need to purchase additional power from other sources in order to meet customer needs. Generating and purchasing power are separate processes, and having enough energy doesn't always equate to having enough power.
Wind can be difficult as a power source because it is intermittent and variable, meaning it is not always consistent in terms of its availability and strength. This inconsistency can create challenges in integrating wind energy into the power grid and can require backup power sources to maintain a stable supply of electricity. Additionally, wind farms need to be located in areas with consistent wind patterns, which may not always be near areas of high energy demand.
Yes, electron microscopes require electricity to operate. They use electrons to generate images at a very high resolution, which requires a high voltage electrical source to accelerate the electrons. Without electricity, an electron microscope would not be able to function properly.
Limited depth of field: Electron microscopes have a narrow depth of field, making it challenging to focus on three-dimensional samples. Sample preparation: Samples for electron microscopy need to be placed in a vacuum and coated with a conductive material, which can distort the natural structure of the sample. High cost and maintenance: Electron microscopes are expensive to purchase, maintain, and operate, requiring specialized training and expertise.
no not always
Microscopes need stage clips in order to hold the slide or specimen in place. However, they are adjustable or removable on some microscopes, which is good, since you don't always need them.
Doctors need microscopes because they need to discover new diseses. Doctors need microscopes because they need to discover new diseses.
His power was unmatched by anybody.They turned the power off.We need to find a way to power up this machine.
We need power to live like we need power for heat to get water run your car keep things cold we would always need it
because if you need to cheek on someone and they are far away use the microscopes to see them
Light microscopes allow you to view living specimens and electron microscopes do not allow this.
Depends a bit on how high power your microscopes are, but probably, yes. You'd need to catch the cells during cell division, however, and then stain with something like Giemsa to make the chromosomes visible for light microscopy. The cells would need to be in metaphase ie. with condensed chromosomes.
because it can always explode right there and then
They use microscopes and eye droppers, beakers and graduated cylinders!
When engine is turned off there won't be any pressure.
Um ... if you can't remember whether you turned it in or not, maybe you need to get some more sleep so you can focus better! If you get a 0, you didn't turn it in. You can always ask the teacher if you really have forgotten.
