What side of the mirror is best used when observing specimens under the prevailing laboratory conditions Why?
The flat side simply reflects light and gives a sharper image. The concave side concentrates the light and provides brighter illumination. It can be difficult to direct the light with a mirror illuminator or it may not be bright enough to do the job.
Which type of microscope is most commonly used by students to observe specimens?
Most student microscopes are classified as light microscopes. In a light microscope, visible light passes through the specimen (the biological sample you are looking at) and is bent through the lens system, allowing the user to see a magnified image.
Is the image always best with the highest illumination?
Is the image always best with highest illumination? Is the same level of illumination best for all magnifications? Higher illumination is better for high power and lower illumination is better for lower power.
Which type of microscope would be best to use to observe unstained bacterial cells the cells are small and no detail is needed?
Unfixed, unstained specimens can be viewed in the electron microscope if they are frozen in hydrated form, a technique called cryoelectron microscopy. The scanning electron microscope can be used to view unsectioned cells or tissues; it produces images that appear to be three-dimensional.
What type of mirror is used in a microscope?
concave mirror
Microscopes: A concave mirror is used in the base of a microscope as a condenser. The light from an external source is shone on the specimen, after being passed through the mirror. The concave mirror concentrates the light on the specimen only to ensure that the surroundings are relatively dark.
Which type of mirror is used in a microscope Why is this so?
Usually, concave mirror or plano concave mirror are used in microscope. The combination of lenses and mirrors used in making the microscope helps in obtaining magnified and sharp image of the objects.
