Submarines primarily use Very Low Frequency (VLF) radio waves for communication while submerged. VLF can penetrate water to a limited extent, allowing submarines to receive messages without surfacing. For more secure and longer-range communication, submarines may also use Extremely Low Frequency (ELF) waves, but these are less common due to their limited data transmission capabilities. When on the surface, submarines can use higher frequency bands, such as HF or VHF, for faster communication.

Why are microwaves not used for communicating with submarines?
Microwaves would be a great way to communicate with submarines, but they'd have to surface to use that method of connecting. Surfacing would defeat the purpose of having the submarine out there, and could easily expose it to detection. We do use radio to communicate with submarines, but not microwaves. Microwave energy has a very limited ability to penetrate water. Very low frequencies can penetrate water to a certain extent, though. And that's why we don't bother with microwaves for submarine communication.
How do ships communicate?
Ships communicate using radios. To be able to use a radio the captain has to have a special cob radio license.
How do submarines communicate in water?
military submarines use low frequency antenna that extends from the sail(conning tower.) The message is typed into a computer, then is sent to another submarines antenna that receives it and displays it on a computer.
Why do some trucks have big antennas?
They use Citizens' Band Radio (CB) to communicate with other truckers on the road. The long antennas give them better reception and transmission.
How do lunar vehicles communicate?
They use radio communication equipment.
Do satellites normally use microwaves or radio waves?
Microwaves are radio waves.Most satellites communicate in microwave radio frequency bands.
How do astronauts communicate in space?
Astronauts mainly communicate in space using radio waves. They use radios to talk to mission control on Earth and to communicate with each other inside the spacecraft. They can also use video conferencing and email for communication purposes.
What did people use to communicate in the 1930s?
they used TV and they also used the radio they had no cell phones
What radio band and speed does 802.11 a use?
5GHz with a speed of up to 54Mbps
Which color of the electromagnetic radiation has maximum transmission in sea?
The military satellites use a blue/green or aquamarine color LASER beam to communicate with submerged submarines.
What applications use a half duplex transmission mode?
Citizens band (CB) radio Two-way radio communication
What can you use to communicate with your family when your on Antarctica?
Depending on the type of support supplied to you there, you may be able to use e-mail or INMARSAT or ham radio to communicate, generally, all over the world.
