this problem is very similar to the first one in this chapter of your textbook where we wanted to know an equation to find wavelength. And now we want to know an equation to find frequency. So all we can do is rearrange the equation we had before. We first said that Lambda is equivalent to C over f. So we want F, which is our frequency so f would be equivalent to see over Lambda. Remember that lambda is our wavelength. C is the speed of light and f is our frequency. So using this equation, we have found frequency. And we can use this equation to find the frequency of our sample or during our experiment. So I hope that this made sense and how I hope this. It's clear how we got to one equation to the one for frequency.
