THE MICROSCOPE

Question 1

The total magnifying power of the compound microscope is the product of the?

Answer 1

magnification of the objective lens and that of the eyepiece

Question 2

-is an instrument that uses one or more lenses to produce a magnified image of an object that is invisible to the naked eye.

Answer 2

MICROSCOPE

Question 3

is the most commonly used microscope in laboratories. It
uses the principle of light microscopy (also called optical microscope) in which it uses natural or artificial transmitted light as the source of light to illuminate an object.

Answer 18

DIAPHRAGM

Question 19

-which transmits light through a translucent object for viewing and controlled by an on/off switcH

Answer 19

ILLUMINATION SYSTEM

Question 20

-You can focus your microscope by using the?

Answer 20

COARSE & FINE ADJUSTMENTS

Question 21

-uses an ultraviolet light source to expose a specimen stained with fluorescent dye resulting in an emission of longer wavelength of light.

Answer 21

FLUORESCENT MICROSCOPE

Question 22

-utilizes a beam of electrons instead of a beam of light used in the light microscopy. The resolution of this is extremely high, theoretically 100,000 times than that of a light microscop

Answer 22

ELECTRON MICROSCOPE

Question 23

-A type of an electron microscope that provides a three- dimensional image of the object as well as high resolution.

Answer 23

SCANNING ELECTRON MICROSCOPE

Question 24

-another type of electron microscopy by which live organisms can be visualized based on rapid cooling of specimens by deep-freezing in liquid gas and the
subsequent formation of carbon platinum replica of the specimen.

Answer 24
