What is the use of the coarse adjustment knob?
The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.
What does the coarse focus knob on a microscope do?
The coarse focus on a microscope is provided to move the instrument quickly to where it is nearly in focus. Some microscopes only have a coarse focus. The fine focus is used to move with slower and more precise adjustment to where the instrument is exactly in focus.
What does the coarse adjustment do on a microscope?
The coarse focus adjustment moves the lens (or the stage, depending on the construction of the microscope). So does the fine adjustment but the fine does it much less and much more accurately (less play in the gears)
What is the large knob on the side of a microscope that should be used first when viewing a slide?
This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.
How does the procedure for using the microscope differ under high power as opposed to low power?
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.
What is the difference between fine-grain and coarse-grain?
Coarse is ruff/hard, and fine grain is smooth/ soft!
Is rhyolite coarse grain or fine grain?
fine grained
What is the difference between coarse-grained and fine-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
What is the difference between fine-grained and coarse-grained?
Fine grained has larger crystals and coarse grained has smaller crystals
What is coarse grain in metals?
Fine grains are harder than coarse grains
Difference between coarse pearlite and fine pearlite?
coarse pearlite structure has better ductility and toughness compared to fine pearlite structure but fine pearlite structure has better strength compared to coarse pearlite structure.
What is meaning the grain of the rock?
fine grained or coarse grained
What is difference between unc tap and unf tap?

Does extrusive have fine grain or coarse grain?
Extrusive igneous rocks generally have a fine grain texture. This is because they cool quickly on the Earth's surface, causing the minerals to form small crystals.
What type of grain do granite and basalt have?
Granite - coarse grained. Basalt - fine grained.
What makes hardwoods hard?
The difference between hardwood and softwood is in the closeness of the grain. For instance the timber that comes from eucalyptus is close and fine grained and is classed as a hardwood. Pine has a loose coarse grain and is a soft wood. Balsarwood as used in model airplanes is also classed as hardwood, because of it's grain not because of it's hardness.
What is the grain size of coal?
The grain size of coal can vary, but it typically ranges from fine particles to larger chunks. Coal can be classified based on its grain size as fine, medium, or coarse coal. The grain size of coal can impact its combustion efficiency and handling characteristics.
