I am looking for formula and easy explanation for calculating the wavelength of a sine wave. So far I have not been able to calculate the example I want to do as I could not understand the resources I've found from Google.
What is the wavelength of sine wave? Given frequency, distance and time.
For instance, a 0.42 MHz sine wave takes 3.3 µs to travel 2500 meters.
I am asking for patience I know this might look amateur for some but I am learning basics and I struggle to find the answer.
