1. The problem statement, all variables and given/known data An FM station broadcasts at 107.5 MHz. What is the wavelength of this wave? 2. Relevant equations well i know that speed = frequency X wavelenght but if i dont know the speed then how can i find the length 3. The attempt at a solution so i found out that the average length of a radio wave is about 3 m and tried it but it was the wrong answer. i am just confused how to find the wavelength with only the frequency.
