Hint:Before going through the question let us first have a bit idea about the given unit of length I.e. Angstrom. A tenth of a millimicron or one ten millionth of a millimetre, is a unit of length used to express electromagnetic wavelengths.

Complete answer:
Description: The angstrom, also known as the \[\text{angstrom}\] (\[A^o\]) is a unit of length equal to \[1 \times {10^{ - 10}}\] metres \[\left( m \right)\] or \[0.1{\text{ nanometers (nm)}}\]. The device is commonly used to express the sizes of atoms, molecules, and electromagnetic wavelengths in physics, chemistry, and biology. In electronic engineering, the unit is often used to test integrated circuit components.

Uses of the Angstrom: Since an atom's diameter is on the order of one angstrom, the unit is particularly useful when discussing the atomic and ionic radius or size of molecules, as well as the distance between planes of atoms in crystals. Chlorine, sulphur, and phosphorus atoms have a covalent radius of about one angstrom, while hydrogen atoms have a radius of about half an angstrom.

In solid-state physics, chemistry, and crystallography, the angstrom is used. The electron microscope is used to calculate light wavelengths, chemical bond lengths, and the scale of microscopic structures. X-ray wavelengths are commonly expressed in angstroms, with values ranging from \[1{\text{ }}to{\text{ }}10.\]

Note: The angstrom unit, on the other hand, is not recognised by the International System of Units\[\left( {SI} \right)\] . It is named after Anders Jonas ngström, a 19th-century Swedish physicist. The angstrom is often used to determine atomic and molecular sizes (most elements have atoms with radii of around\[1{\text{ }}to{\text{ }}2\]), as well as the thickness of liquid film thickness.
