Fuzzy images viewed with a microscope may be due to poor resolution. In microscopy, the resolution is defined as the smallest distance between two points on a specimen that can still be defined as two separate objects.

Why must you dry your slide before putting it on the stage of the microscope?

Drying the slide before placing it on the microscope stage helps prevent water droplets from distorting the sample or affecting the quality of the image. Water can create a barrier between the objective lens and the sample, leading to poor resolution and focus. Additionally, drying the slide helps prevent the growth of microorganisms that may otherwise thrive in a moist environment.


Who uses the microscope?

The first record of the use of lenses to manipulate images was in Greek and Roman writings of around 1000 A.D. As for the origins of someone using lenses to magnify a minute object, it is unclear. Most scientific instruments have a clear place in the historical records when they were formed and who created them, not the microscope though. The definition of the microscope makes it difficult to determine when it was first created. Since there were lenses dating back to ancient societies, how do we say when those lenses were used to look at minute objects? It is practically impossible to say when a single lens was used in that fashion. Credit for the first compound microscope (multiple lenses) is generally given to Zacharias Jansen and John Lippershey of the Netherlands, in 1590. It is likely that the microscope was a result of work made on the telescope. The telescope had much more practical uses in that time, because it could be used for maritime navigation.This idea is supported by the account of one of the first compound microscopes, which was six feet long and had a one inch barrel with a lens at either end. After the compound microscope the next major development was in lenses. Half a century after the compound microscope, both Anthony van Leeuwenhoek and Robert Hooke realized that lenses with very short focal lengths was the key to more magnification. This meant the use of extremely double convex or spherical lenses. They also used lenses made of pure quartz, creating a more pure glass instead of the poor quality, greenish glass of the day. The problem of making lenses in this fashion was that it created chromatic aberration. This aberration is because different wavelengths of light are refracted different amounts, resulting in a smeared image instead of a clear one. In 1758 John Dollard patented an achromatic lens. Even with this new lens, it was not until 1930 when Lister was able to use it to alleviate the problem of chromatic aberration. Much of the interim time was spent on telescope technology. Another form of the microscope, first proposed by Isaac newton in 1692, is the reflecting microscope. In this case the light would not pass through a lens, but would reflect off of a concave mirror. Since all light is reflected the same, there would be no problem with chromatic aberration. The first reflecting microscope was made by Barker in 1736. This model was developed directly from reflecting telescope designs. Reflecting microscopes are used today, but the transmission type are much more prevalent.


What is the condition known as an abnormal increase in the outward curvature of the thoracic sp ine as viewed from the side?

The condition you are referring to is called kyphosis. It commonly results in a hunched or rounded back posture and can be caused by factors such as poor posture, osteoporosis, or congenital issues. Treatment options may include physical therapy, bracing, or in severe cases, corrective surgery.


Which imaging system combines tomography with radionuclide tracers to produce enhanced images of selceted body organs or areas?

The imaging system that combines tomography with radionuclide tracers to produce enhanced images of selected body organs or areas is call PET or positron emission tomography. These types of scans are most commonly used check for brain function, poor blood flow and cancer.


Why are microorganisms hard to see in wet preparations?

Microorganisms are hard to see in wet preparations because they are transparent, making them difficult to distinguish from the surrounding fluid. Additionally, the high water content in wet preparations can distort the light passing through the microscope, leading to poor visibility of microorganisms. Staining techniques are often employed to improve contrast and visibility of these organisms in wet preparations.

Can a specimen be viewed under a microscope using the 100x objective without a coverslip?

No, a specimen should not be viewed under a microscope using the 100x objective without a coverslip. The 100x objective requires a thin layer of immersion oil to properly focus light and achieve the necessary resolution. Without a coverslip, the specimen may be too far from the lens, resulting in poor image quality and potential damage to both the specimen and the objective lens.

What are fuzzy black molds?

Fuzzy black molds are a type of mold that appears dark and has a soft, fuzzy texture. They are typically found in damp areas with poor ventilation, such as bathrooms, basements, and kitchens. These molds can cause health issues if inhaled, so it's important to address any mold growth promptly.

Why is the specimen prepared for a monocular microscope must be very thin?

The specimen must be very thin for a monocular microscope because light has difficulty passing through thick specimens, leading to poor image quality and decreased clarity. A thin specimen allows more light to pass through, resulting in a sharper and more focused image when viewed through the monocular microscope.
