Question

I need help with this science problem

Answer 1

The formula is given, so this is basically a plug and chug problem.

Given values:

$\lambda=530*10^{-9}\text{ m}\\c=3.0*10^8\text{ m/s}$

Plugging these values into the given equation, we get:

$f=\frac{c}{\lambda} =\frac{3.0*10^8\text{ m/s}}{530*10^{-9}\text{ m}} =1.8265*10^{17}{\text{ s}}^{-1}=1.8265*10^{17}\text{ Hz}$

This is a 2 sig fig problem, so your final answer should be $1.8265*10^{17}\text{ Hz}$.
