Answer:

570 nm

Step-by-step explanation:

The wavelength of an electromagnetic wave is given by:

$\lambda=(c)/(f)$

where

$c=3.0\cdot 10^8 m/s$ is the speed of light (the speed of the electromagnetic waves in a vacuum)

$f=5.26\cdot 10^(14) Hz$ is the frequency of the emitted light

Substituting the numbers into the equation, we can find
$\lambda$ , the wavelength of the emitted light:

$\lambda=(3\cdot 10^8 m/s)/(5.26\cdot 10^(14) Hz)=5.70\cdot 10^(-7) m = 570 nm$
