The main motive of this paper is to use C programming language for the calculations of distances of AM and FM waves based on their frequencies and powers. Previous papers have predominantly addressed different methods and formulas for finding the distance, yet an easy way to know it remains underexplored. The process behind the transmission is, the AM or FM waves are transmitted using different modulation techniques through transmission towers in the form of carrier waves and received through receiving antenna by demodulation. The findings hold the practical significance for diverse communication situations by finding the travelling range of AM and FM waves. This paper contributes to the people, whose works are based on signal transmissions, by easily knowing the travelling range of AM and FM waves of various frequencies and powers they can easily plan, where to construct new towers for transmission and can know the range of already constructed towers, facilitating applications in fields such as communication, engineering and signal transmission.
