Concept explainers
(a)
Interpretation:
The two most common types of SPMs and the difference between them are to be stated.
Concept introduction:
The scanning probe microscopic has enough capability to resolve the details of the surfaces down to the atomic level. The scanning tunneling microscope is the first example of the SPMs. After the scanning tunneling microscope the second type of SPMs is atomic force microscope.
(b)
Interpretation:
The advantages of scanning tunneling microscope and the atomic force microscope are to be stated.

By adjusting the length of the latter until the transmission through the two cells is the same. the concentration of the second solution can be inferred from that of the former. Suppose that a plantdye of concentration 25 μg dm-3 is added to the fixed cell. the length of which is 1.55 em. Then a solution of the same dye. but of unknown concentration. is added to the second cel l. It is found that the same t ransmittance is obtained when the length of the second cel l is adjusted to 1.18 em. What is the concentration of the second solution?arrow_forward
