# 560 nm is how many meters?

Sep 6, 2016

560 nm is $5.6 \times {10}^{-} 7$ 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 $1 \times {10}^{-} 9$ m, then 560 is $560 \times {10}^{-} 9$

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 $5.6 \times {10}^{-} 7$ m.
