Which type of modification of radio waves sends signals the farthest?
Rascal77
The working distance depends a lot on the receiver that's being used to pick it up.
The Pioneer-11 spacecraft was launched in 1973. The last radio contact with it
occurred in 1995, when it was 4 billion milesfrom Earth. Communication might
have laster longer, but its on-board power source ran out of gas at that point.
The spacecraft transmitted just a few watts of radio power, at microwave
frequencies. But the antennas that were used to receive its signals are dishes
hundreds of feet across, with supercooled electronics.

What do radio waves bounce off?
Radio waves are reflected by many solid objects, such as wood, stone, and notably metal, allowing the use of microwaves in radar applications.Also importantly in broadcast radio, the ionosphere (an upper layer of the Earth's atmosphere) can bounce signals back down to locations beyond the line-of-sight horizon.

What The Hypothalmous sends signals to?

How do wireless antennas share information?
they dont. An antenna is simply a piece of metal hooked to a device (normally a radio or a walkie-talkie). A receiver (for example, a radio) pick up electrical signals from the antenna, and a transmitter sends them to the antenna. They can be combined to form a transceiver which then sends and receives signals from the antenna.
What does a wifi antenna do?
It sends and receives radio signals to and from other wireless devices. Similar to a CB radio only in computer language.
