EVERYDAY SCIENCE

Detailed explanation-1: -The receiver was called a wireless because there were no wires linking to the the transmitting station. It was called radio because the transmitting station radiated electromagnetic waves.

Detailed explanation-2: -Its basic principle is: Two objects vibrating at the same frequency are capable of transmitting energy, and this process does not affect objects that vibrate at different frequencies. [3] The oscillating circuit excites the induction coil to generate an alternating magnetic field.

Detailed explanation-3: -In radio communication systems, information is carried across space using radio waves. At the sending end, the information to be sent is converted by some type of transducer to a time-varying electrical signal called the modulation signal.

Detailed explanation-4: -Wireless transmission is a form of unguided media. Wireless communication involves no physical link established between two or more devices, communicating wirelessly. Wireless signals are spread over in the air and are received and interpreted by appropriate antennas.
