The term “nanometer” refers to how many divisions of one micrometer (i.e., how many nanometers are in one micrometer)? 1000 1000000000 10 1000000
The Correct Answer and Explanation is:
The correct answer is 1000.
Here’s why:
A micrometer (µm) is equal to one millionth of a meter (1 µm = 10^-6 meters), while a nanometer (nm) is one billionth of a meter (1 nm = 10^-9 meters).
To understand how many nanometers are in a micrometer, you can divide the value of one micrometer (10^-6 meters) by the value of one nanometer (10^-9 meters).10−6 meters10−9 meters=1000\frac{10^{-6} \, \text{meters}}{10^{-9} \, \text{meters}} = 100010−9meters10−6meters=1000
This means that 1 micrometer contains 1000 nanometers.
Example:
- A micrometer measures distances on the scale of cells, bacteria, or tiny parts of a machine.
- A nanometer, which is much smaller, is commonly used in the field of nanotechnology, where distances are measured on the scale of individual molecules, atoms, or the wavelength of light.
So, the nanometer is much smaller than the micrometer, and for every micrometer, there are 1000 nanometers.
This relationship helps in many fields of science, such as physics, biology, and chemistry, to measure objects at different scales.
