What are the changes in the field of view and the amount of available light when going from low to high power using the compound microscope?
Answer:When going from low to high power using the compound microscope, the field of view and the amount of available light changes. The field of view narrows down and gets smaller as the objectives uses higher power. Also, the amount of available light decreases when going from low to high-power objectives.
How does the field of view change as you go from low to high power?
Going to high power on a microscope decreases the area of the field of view. The field of view is inversely proportional to the magnification of the objective lens. The specimen appears larger with a higher magnification because a smaller area of the object is spread out to cover the field of view of your eye.
What changes the amount of light on a microscope?
IRIS DIAPHRAGM CONTROL — A lever (or rotating disk) that adjusts the amount of light illuminating the slide.
What happens to the field of view as the magnification increases?
In short, as magnification increases, the field of view decreases. When looking through a high power compound microscope it can be difficult to determine what you will see through the eyepieces at different magnifications.
What happens as the power of magnification increases?
As you increase the magnification by changing to a higher power lens, the working distance decreases and you will see a much smaller slice of the specimen. Look at the lenses on your microscope, and note that as the magnification increases, the length of the lens increases and the lens aperture decreases in size.
What is the function of HPO in microscope?
The high-powered objective lens (also called “high dry” lens) is ideal for observing fine details within a specimen sample. The total magnification of a high-power objective lens combined with a 10x eyepiece is equal to 400x magnification, giving you a very detailed picture of the specimen in your slide.
