How far do fm radio waves travel
WebWe invented a new, inexpensive device to measure distances up to 1.5km (about 1 mile) with accuracy about ±5 Meter (15 feet). The use of radio waves makes it possible to measure without the target being in sight. Web14 sep. 2024 · In general, radio waves can travel a long distance in a short amount of time. For example, a strong FM radio signal can travel up to 100 miles in one second. However, the distance that a radio wave can travel also depends on the environment in which it is travelling. For example, if there is a lot of interference or if the signal is travelling ...
