Question: 1 Nanometer \(=\text{ ?}\) A. \({{10}^{-3}}\) m B. \({{10}^{-6}}\) m C. \({{10}^{-9}}\) m D....

1 Nanometer = ?=\text{ ?}
A. 10−3{{10}^{-3}} m
B. 10−6{{10}^{-6}} m
C. 10−9{{10}^{-9}} m
D. 10−12{{10}^{-12}} m

Explanation

Solution

A nanometer is a very small unit of length. In addition, it is equivalent to only one-billionth of a meter. It is multiples of 10 in the form of 10x{{10}^{x}} where xx represents the number of zeroes present in the number.

Step by step answer: A known 1 nanometer is equivalent to 10−9{{10}^{-9}} m.
Hence, the correct option is option C
A nanometer is a unit for measuring length. A nanometer is used to measure things that are very tiny. Atoms and molecules which are the smallest pieces of matter around us are measured in nanometers. For example, the size of a water molecule is less than a nanometer. Certain bacteria are just a few nanometers wide. This unit is used to measure even larger things like the hair is about 100,000 nanometers wide.
Additional information:
There are other units which measure small lengths. They are as follows:
A Fermi is a very, very small unit of length. In mathematical notation, it is 10−15{{10}^{-15}} m.
A picometer is one-thousandth of a nanometer. In terms of meter, it is 10−12{{10}^{-12}} m.
An Armstrong is one ten-billionth of a meter. In mathematical notation, it is 10−10{{10}^{-10}} m.
A micrometer is one-millionth of a meter. In mathematical notation, it is 10−6{{10}^{-6}} m.
A millimeter is one- thousand of a meter. In mathematical notation, it is 10−3{{10}^{-3}} m.

Note: The whole branch of science which deals with nanoparticles or particles with molecules ranging from 1 to 100 nanometers. This branch is known as nanotechnology. It is a branch evolved from the modern science experiments and field of study and has been a potential field for further benchmarks.
