Hello!

We have the following data:

f (radiation frequency) =
$3.0*10^(19)\:Hz$

v (speed of light) =
$3.0*10^8\:m/s$

λ (wavelength) = ? (in m)

Let's find the wavelength, let's see:

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

$3.0*10^(19) = (3.0*10^8)/(\lambda)$

$\lambda = (3.0*10^8)/(3.0*10^(19))$

$\boxed{\boxed{\lambda = 1*10^(-11)\:m}}\Longleftarrow(wavelenght)\end{array}}\qquad\checkmark$

I Hope this helps, greetings ... DexteR! =)
