With scanning probe microscopy technology, we see not actual atoms but rather images of them. Explain

ok

When wee something basically we see light rays coming to our eyes after getting reflecting from that something. But the scanning tunneling microscope does not use light
to produce its images. Instead, it takes a series of measurements
of the position of its probe as the probe passes over an object.
These are very small objects, and the measurements are very
tiny. When you put all of these measurements together, you end
up with a map of the surface. This map is the 'image' that we see.
In other words, we are not seeing the object directly, but rather we
are seeing the indirect mapped image because it has been constructed
from lots and lots of data measurements assembled inside the
computer of the STM.

Got it ?

i think so

welcome back
OpenStudy (abhisar):
Lets understand this with the help of an example

Suppose u want to know how pentagon looks !

There are two ways of doing that
1) u will hire a chopper (don't know if u already own one) and see it from above with ur eyes.
2) u'll google its dimensions and draw it's figure on a paper !
OpenStudy (abhisar):
2nd one is STM !
OpenStudy (anonymous):
STM?
OpenStudy (abhisar):
Is something clear ?
OpenStudy (abhisar):
STM= Scanning microscopy

Scanning microscopy takes series of measurement of its probe. These measurements are very tiny. All the collected data are analysed by a computer to make a map/image of the object

Got it ?
OpenStudy (anonymous):
yep
OpenStudy (abhisar):
SURE ?
OpenStudy (anonymous):
yep
