What is the equivalent of 5000 angstroms in nanometers?

To determine the equivalent of 5000 angstroms in nanometers, it's important to understand the relationship between the two units of measurement. An angstrom is a unit of length that is equal to one ten-billionth of a meter (1 Å = 10^-10 meters), while a nanometer is equal to one billionth of a meter (1 nm = 10^-9 meters).

Since 1 nanometer is equal to 10 angstroms, the conversion from angstroms to nanometers can be conducted by dividing the number of angstroms by 10. Therefore, to convert 5000 angstroms into nanometers:

5000 angstroms ÷ 10 = 500 nanometers.

This calculation clearly shows that the equivalent of 5000 angstroms is 500 nanometers, making it the correct choice.

Other options reflect incorrect conversions or miscalculations based on the size hierarchy, but the correct relationship between angstroms and nanometers leads to 500 nanometers as the right answer.
