a type of image that connote be viewed directly is called a _____ image virtual
a _____ microscope consists of two lenses mounted at each end of a hollow tube compound
the lens closest to the specimen is called the _____ objective lens
the lens nearest the viewers eye is called the eye piece of ocular lense
the image seen through a compound microscope is _____ virtual
the coarse and fine adjustments are part of the microscopes mechanical system true
a transparent specimen is viewed through a microscope using _______ light (light passes through specimen) transmitted illumination
an opaque object requires _______ illumination for viewing with a microscope verticle or reflected
a ______-- collects light rays from the base illuminator and concentrates them on the specimen condenser
a microscope that remains in focus regardless of which objective lens is rotated into place is _____ parfocal
a microscope with only oe eyepiece is ---- monocular
a microscope with two eye pieces is ---- binocular
each microscope lens is inscribed with a number signifying its ___ magnifying power
an eyepiece lens of 10x used in combination with an objective lens of 20x has a total magnification power of _____ 200x
the ability of an objective lens to resolve details into separate images is directly proportional to its ------ numerical aperture
the size of the specimen area in view is known as the ------ field of view
as magnification increases the field of view ____ decreases
the thickness of a specimen in view is known as the ____ depth of focus
the depth of focus _____ with increasing magnification decreases
a side by side view of two specimens is best obtained with the _____ microscope comparison
a bridge is used to join two independent objective lenses into a single binocular unit to form a comparison microscope true
two monocular compound microscopes properly spaced and aligned describe the ______ microscope steroscopic
the stereoscopic microscope is the least frequently used microscope in a typical crime laboratory false
light confined to a single plane of vibration is said to be plane polorized
the _______ microscope allows a viewer to detect polarized light polerizing
by using the _______ one can view a particle under a microscope while a beam of light is dissected at the particle in order to obtain its absorption spectrum microspectrophotmer
when a beam of electrons strikes a specimen _____ are emitted whose energies correspond to elements present in the specimen. x-rays

two lenses mounted at the end of a tube with magnification of up to 1500x compound microscope
eye lens piece, lens nearest to the eye ocular lens
light reflects off specimen into lens reflected illumination
light passes through specimen transmitted illumination

microscope has two eye pieces binocular
magnification beyond which no greater resolution of an image is seen empty magnification
area seen throughout he lenses in the eyepiece field of view
thickness of specimen which can be oberverd depth of focus
two compound microscopes connected in such a way that the field of view includes objects being examined under each objective lens comparison microscope
microscope designed to allow viewing of object in three dimensions steroscopic microscope
uses polarized light to allow viewing of object in a different way polarizing microscope
device which lets a scientist view a microscopia crystal and simultaneously pass a beam of light through it for the purpose of determining its absorption spectrum microspectrophotometer
