Answer:
Option C. 16.6 m/s
Explanation:
To round this 16.558 m/s to 3sf, we need to count the number beginning from 1. When we get to the 3rd number( ie 5), we'll examine the fourth number(i.e 5)to see if it less than five or greater. If it less than five, then we'll discard it. But if it five or greater, we'll approximate it and add it to the 3rd number.
So.
16.558 m/s = 16.6m/s to 3sf
I believe it's diffraction because it can be nothing else except this ;)
We know, Frequency = speed / wavelength

f = 426.25 Hz
In short, Your Answer would be 426.25 Hz
Hope this helps!
