Web• If you are using the radio primarily outdoors with clear line-of-sight, then VHF is a better choice because it's signal will travel farther. • If you are using the radio in or around … WebApr 10, 2024 · Low to Medium Frequency Range of Radio Waves ELF radio waves, the least of every frequency of radio waves, have a long-range and are valuable in entering water and rock for correspondence with submarines and inside mines and caves. The most remarkable common wellspring of ELF/VLF waves is lightning.
WebIn sea water, radio waves don't travel too far but microwaves might do better because sea water isn't a "good" conductor any more at those frequencies. On the other hand, sound waves travel through water very well so submarines use sonar rather than radar. Click Here to return to the search form. WebMay 3, 2024 · VLF radio waves (3–30 kHz) can penetrate seawater to a few tens of meters and a submarine at shallow depth can use them to communicate. A deeper vessel can …

WebApr 10, 2024 · They can travel through air, solid objects, and even space, making them very useful for a lot of technologies. When you listen to the radio, connect to a wireless network, or cook dinner in a microwave oven, you are using electromagnetic waves. Radio waves and microwaves are two types of electromagnetic waves.
WebFeb 3, 2016 · The size of a photon’s wave – its wavelength – tells you about its energy. Figure 1 shows waves with two different wavelengths. If the wave is long, it does not have much energy; if it is short, it has a lot of energy. Radio waves do not have much energy, and that means they travel in big waves with long wavelengths. hufflepuff girls in harry potterWebHowever, when locating objects underwater, light and radio waves are attenuated rapidly when they travel through water, which is why ultrasound is the most viable option to locate underwater objects.
