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.
