Which objective should be use first in viewing an object?
I assume this is a question about viewing an object through a compound microscope. Always use the shortest objective lens (that is the one with the lowest magnification) first. Focus the lens and then when you want more detail or a closer view, you can simply rotate the lens turret to a longer lens and it should be nearly in focus. Use the fine focus feature to sharpen the picture. If an object is viewed in this way, the danger of scratching the high power objective by ramming it into the slide is lessened.
When looking at a specimen for the fir ts time under a microscope do you view with high power objective or lowest objective fir ts?
first view with low power then gradually increase the power. hope it helped you!
What are a few facts about the microscope?
Microscopes are used to see objects too small for the human eye. One of the first microscopes was made in 1590 by Zaccharias and Hans Janssen. Galileo later improved their invention in 1609. Three types of microscope: -Optical (uses visible light wavelengths) -Electron (uses electrons to magnify the object) -Scanning probe (uses a physical probe)
Who showed that all objects in the universe attract each other through gravitational force?
Isaac Newton was the first to propose that there is a universal gravitational force which affects all objects in the universe.
Who made the first observations of objects in the solar system that orbited neither the sun nor earth were made by?
the first observations of the solar system were made by the mayans

Why should you always view the slide at scanning power first?
Viewing a slide at scanning power first allows for a broader overview of the specimen, making it easier to locate regions of interest before switching to higher magnifications. This approach helps prevent damage to the slide or the microscope objective by minimizing the risk of accidental contact. Additionally, it provides context for the details observed at higher power, enhancing the overall analysis of the specimen.
in scientific method which should come first?
The first step in the Scientific Method is to make objective observations
Why should you always use the low powered objective lens to locate objects mounted on the slide first even if you want to observe them with the high power objective lens?
If you don't a couple of things can happen, you can break or crush the slide and you just will not be able to find it. It would be like trying to find a bird in a tree when flying above the forest. You have to locate that tree first.
What is the first website listed when googling "scanning services"?
The first non-ad website when googling "scanning services" is http://www.imagingconnections.com/. This website provides a document scanning service, and you can request a quote from them.
When focusing a specimen you should always start with the?
When focusing a specimen, you should always start with the lowest magnification objective lens, typically the scanning objective (4x or 10x). This allows for a broader field of view, making it easier to locate the specimen. Once the specimen is centered and in focus at low magnification, you can then switch to higher magnification lenses for more detailed observation. Always use the coarse focus knob first, followed by the fine focus knob for precision.
When you can know the pregnancy by scanning?
Usually ur first scan will be at 12 weeks ur doctor should sort it for u
Which objective would be better to use when using a scanning slide?
A good objective to use for scanning a slide would be a low magnification objective such as 4x or 10x. These objectives provide a wide field of view and are ideal for quickly surveying large areas of a specimen on the slide.
Should you include an objective when writing your first resume?
Yes , that will be very good , when the interviewers see the objective resume , he will give you a high points and you can get employed .
What are the magnifications on the objective lenses?
There are many different microscopes currently on the market. Most of these microscopes come with different levels of magnification so that you can view an object in different ways. It is important to make sure the microscope you choose to use will have the correct maginfication you need.
When was the scanning electron microscope invented?
The scanning electron microscope was invented in the 1960s. The first commercial scanning electron microscope was introduced in 1965 by Cambridge Instruments.
When focusing a microscope what do you start with?
When focusing a microscope, you should start with the lowest power objective lens, typically the scanning objective (4x or 10x). This allows you to locate the specimen easily and focus without risking damage to the slide. Once the specimen is centered and in focus, you can switch to higher power objectives for more detailed viewing. Always use the coarse focus knob first, followed by the fine focus knob for precise adjustments.
