Respuesta :
Radio communication can travel from Earth to the moon and return in about 2.5 seconds.
This is due to the fact that radio signals move at a speed of roughly 300,000 km/s and that there are 350,000 km between the Earth and the moon. Therefore, the total travel time is 1.25 seconds there and 1.25 seconds back.
The longest electromagnetic spectrum’s wavelengths that are found in radio waves are mostly found at frequencies of 300 gigahertz and below. The wavelength for 300 GHz is 1 mm, while the wavelength for 30 Hz is 10,000 kilometers.
What are radio waves and how do these radio waves work?
Radio waves are electromagnetic radiation types that are most commonly used in communication devices like radios, mobile phones, and televisions.
These gadgets are designed to take in radio waves and then transform them into sound waves by causing mechanical movements in the speaker.
How are radio waves produced?
Electromagnetic waves are sent and received by the radio equipment in order to operate. An extremely fast-moving electrical current makes up the radio signal.
This field is broadcasted by a transmitter by using an antenna. After this, a receiver picks up the field and then converts it to the audio heard on the radio.
