Question

560 nm is how many meters?

Answer 1

560 nm is `5.6xx10^-7` m.

Explanation:

nm, or nano-meters, is converted to meters by using the negative exponents since we're converting a small measurement to a larger one.

if 1 nm is `1xx10^-9` m, then 560 is `560xx10^-9`

in scientific notation; we reduce 560 to 5.6 for convenience.

we divided 560 by 100, the exponent for 100 is `10^2`

add the exponent `x^2` to `x^-9` and you get the exponent `x^-7`

and `x=5.6` so 560 nm is `5.6xx10^-7` m.
