Astudent has an unknown sample. how can spectroscopy be used to identify the sample?

a. it can identify the elements in the sample.
b. it can determine the number of electrons in the sample.
c. it can determine the ratio of the elements in the sample.
d. it can determine the molecular structure of atoms in the sample.

Option (A)

Explanation:

Spectroscopy is that branch of science that enables the astronomers to calculate  the temperature and density of an object, composition and motion of an object when it interacts with the electromagnetic radiations. The Infrared spectroscopy is a type of spectroscopy that helps in the identification of atoms and molecules that are present inside the object.

Thus, the spectroscopy is mostly used in order to identify elements that are in the sample.

Hence, the correct answer is option (A).
