Hint: To find the relation between a nanometer and an angstrom we express them in terms of a common unit of measurement like meters and make a relation between them.
Step By Step Answer :
A nanometer is a unit of measurement length in the metric system which is one billionth of the standard unit of measurement “meter”.
It is denoted by ‘nm’.
It can be expressed as 1 nanometer = m. --- (1)
It is a part of the S.I system of units.
A nanometer is generally used to measure very small distances like the size of molecules or while observing germs under an electronic microscope.
An angstrom is a unit of measurement length in the metric system which is one ten-billionth of the standard unit of measurement “meter”.
It is denoted by .
It can be expressed as 1 angstrom = m. --- (2)
It is not a part of the S.I system of units.
An angstrom is generally used to measure very small distances like the wavelength of a light wave etc.
Therefore from equation (1) and (2), we get
Hence the relation between a nanometer and an angstrom is that one nanometer is equal to ten times of an angstrom.
Note: In order to solve this type of questions the key is to know the definitions of angstrom and nanometer. Once we know the definition we write it in terms of a single unit and form a relation between them.
Just like angstrom and nanometers are units of distance for very small measurements, there are a few units which are used to measure very long distances. They are –
Nautical mile, it is a measurement used in marine and space navigation. 1 nautical mile = 1852 m.
Light year, it is defined as the distance a light ray travels in one year. 1 light year = 9.4607 × Km.
