The first radio was invented by gugliemo marconi but jc Bose who first showed that radio signals could be sent over long distances without wires. Radio was invented in i921.Ansered byvaibhav gupta
Triton is Neptune's moon. However, it takes about 155 min for sunlight to reach Triton.
Amplitude Modulation and Frequency Modulation. They are different methods of transmitting radio signals. AM is good for transmitting radio signals long distance FM is good for transmitting radio signals short distances but better quality
How do THEY get back to earth?!

Earth has been broadcasting radio signals into outer space since the late 1800's.
so people could communicate over long distances
Radio antennas work by converting electrical signals into electromagnetic waves that can travel through the air. When a radio station transmits a signal, the antenna sends out electromagnetic waves. When a radio receiver picks up these waves, the antenna converts them back into electrical signals that can be processed and heard as sound. This process allows for the transmission and reception of radio signals over long distances.
Radio waves are typically diffracted around hills due to their long wavelengths. This diffraction allows radio signals to bend over obstacles and reach areas that would be inaccessible if the waves traveled in a straight line.
The ionosphere is the layer in the Earth's atmosphere responsible for bouncing back radio signals. It is composed of charged particles that reflect radio waves, allowing for long-distance communication via radio transmissions.
From what I have researched, the answer to that is the Ionosphere-upper mesosphere/ lower thermosphere, though I do not know if that is 100% correct.
