WebWhen EM waves travel from air to water or water to air, there is a refraction loss due to the change in the medium. This loss can be calculated from the following formula: Refraction … WebJun 5, 2013 · Electromagnetic waves cannot travel through electrical conductors: this means that in most cases radio waves cannot be used to communicate under water. Anyway, studies have proven that the chance to transmit radio signals under water mainly depends on two factors: the conductivity of water and the frequency of the radio wave.
WebContacts made by submarines are often dozens of miles away, and radar would have to be EXTREMELY powerful to reach that far in water, while sound (a mechanical wave) can …
WebRadio propagation is the behavior of radio waves as they travel, or are propagated, from one point to another in vacuum, or into various parts of the atmosphere.
