Long radio waves, typically in the frequency range of 30 kHz to 300 kHz, use large antennas for transmission and reception due to their long wavelength. These waves are often utilized in AM broadcasting, maritime communication, and navigation systems. Their ability to diffract around obstacles and travel long distances makes them particularly effective for reaching remote areas. Additionally, long radio waves can penetrate through the ionosphere, allowing for communication beyond the horizon.

What is the longest wavelengh in the electromagnetic spectrum?
The electromagnetic waves with the longest wavelength are called "radio waves". There is no limit to how long the wavelengths can be.
This layer is responsible for the possibility of radio communication?
The ionosphere is the layer responsible for enabling long-distance radio communication by reflecting radio waves back to Earth. Its charged particles interact with radio waves, bending and reflecting them to facilitate communication over long distances. Without the ionosphere, radio waves would continue into space, limiting long-distance communication possibilities.
What layer of the atmosphere reflects radio waves?
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
What kind of telescopes do radio telescopes use?
Radio telescopes use parabolic dishes to collect and focus radio waves from space. The dish reflects the radio waves to a receiver, which then converts the waves into electronic signals that can be processed and analyzed.
How do you people use radio waves?
Radio waves have the longest wavelengths in the electromagnetic spectrum. These waves can be longer than a football field or as short as a football. Radio waves do more than just bring music to your radio. They also carry signals for your television and cellular phones
How do humans use radio waves?
Communications over long distances are economically achieved by the utilization of radio waves.
Why do we use radio?
Communications over long distances are economically achieved by the utilization of radio waves.
Do car keys use radio waves?
yes,they do use radio waves
Is Radio waves long?
================================================
What is is radio sound heard through the use of?
Radio sound is heard through the use of radio waves, which are electromagnetic waves that can carry information from one point to another. These waves are transmitted from a radio station and received by a radio receiver, such as a radio or smartphone, which then converts the waves into sound waves that we can hear.
Do walkie talkies use radio waves?
Yes. A good rule of thumb is that if the device has an antenna, it uses radio waves. An antenna would not be needed if it didn't use radio waves.
What is a radio wave?
Radio waves are electromagnetic waves. The radio waves have the longest wavelengths in the electromagnetic spectrum. A radio wave has a much longer wavelength than does visible light. We use radio waves extensively for communications.
What is the use of radio waves?
hearing FM and am news in radio
What types of waves do mobile phones use?
radio waves.
Which have longer wavelength radio waves or light waves?
Radio waves have a far longer wavelength than visible light. The radio waves that do the cooking in your microwave oven are as long as roughly 310,000 waves of blue light placed end-to-end. The radio waves transmitted by an AM station at 1400kHz on your AM dial are roughly 550 billion times as long as blue-light waves.
A device used to detect radio waves from space?
they use radio waves to pick up some what satellite images or existance of things in space
What type of waves does a cellphone use?
Cellphones use radio waves for transmission and reception of signals. These waves are a type of electromagnetic radiation that falls within the radio frequency range.
