The unit of measuring the wavelength is known as an atom A° and is given by $1 A° = \frac{1}{10000000000}$ M. What is the distance of 620 A° units?
Given :
$1 A° = \frac{1}{10000000000}$
To do :
We have to find the distance of 620 A° units.
Solution :
$1 A° = \frac{1}{10000000000}$
$ = \frac{1}{10^{10}} = 10^{-10} M$.
The distance of $620 A° = 620 \times 10^{-10} M = 6.2 \times 10^{-8} M$.
Therefore, the distance of 620 A° is $6.2 \times 10^{-8} M$.
