Lesson 5 Compound Microscope

Question 1

has high magnification but lower resolution resulting to a less sharp image
compared to some advanced types of microscopes.

Answer 1

Compound microscope

Question 2

is the
ability of a microscope to see a tiny object 1000 times.

Answer 2

Magnification of a microscope

Question 3

on the other hand is the ability to
distinguish details or to see two close objects as two distinct objects.

Answer 3

Resolution

Question 4

Attached to a rotating nose piece, or turret, at the base of the body tube are a group of 3 or 4 objectives. focus the light that comes through the specimen, up the body tube, and through the oculars.

Answer 4

Question 9

The surface or platform on which you place the microscope slide

Answer 9

stage

Question 10

Is an opening in the center of stage

Answer 10

stage aperture

Question 11

microscopes that has a movable stage

Answer 11

mechanical stage.

Question 12

The area under the stage, may contain a diaphragm, a condenser, or both.
.

Answer 12

Substage

Question 13

regulates the amount of light passing from the light source through the specimen and through the lens system of the microscope.

Answer 13

Diaphragm

Question 14

The light source, usually an electric lamp, which transmits light through a translucent object for viewing and controlled by an on/off switch.

Answer 14

The illuminating system

Question 15

You can control the amount of light entering the specimen by adjusting what?

Answer 15

diaphragm

Question 16

The flat side of the mirror is usually used with what?

Answer 16

the scanning and low-power objectives

Question 17

The concave mirror is used with what?

Answer 17

higher power objectives

Question 18

The light source for the mirror
.

Answer 18

a lamp

Question 19

The light source for the mirror
.

Answer 19

a lamp

Question 20

can be used as light source but it is not preferred because its intensity is too variable.

Answer 20

natural light

Question 21

. You can focus your microscope by using this

Answer 21

Coarse and fine adjustment knob

Question 22

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

Answer 22

Fluorescent microscopes

Question 23

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

Answer 23

Electron microscope

Question 24

a type of an electron microscope that provides a threedimensional image of the object as well as high resolution.

Answer 24

Scanning electron microscope

Question 25

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 25

Freeze-etching
