RF energy is transmitted through an electromagnetic field. Once the field meets the receiving antenna, voltages are produced by using the antenna as a conductor. RF voltages induced by the antenna are passed on to the receiver then reconverted to transmitted RF information.
The seven basic forces of nature are gravity, electromagnetism, the weak nuclear force, the strong nuclear force, friction, tension, and buoyancy. These forces govern the interactions between objects and particles in the universe.

The two basic divisions of physics are classical physics and modern physics. Classical physics deals with the macroscopic world and includes mechanics, thermodynamics, and electromagnetism. Modern physics focuses on the behavior of particles at the atomic and subatomic levels, encompassing quantum mechanics and relativity.
There are four fundamental forces in the universe: gravity, electromagnetism, the strong nuclear force, and the weak nuclear force. These forces govern how matter interacts at both macroscopic and microscopic scales.
Physical science is the study of non-living systems, focusing on the interaction of matter and energy. Its basic principles involve understanding the nature of matter, the behavior of energy, and the laws that govern their interactions, such as the laws of thermodynamics and Newton's laws of motion. Physical science aims to explain the natural world through observation, experimentation, and the formulation of theories and models.
That will depend on your location and the signal strength of your antenna. Use *1 for help in figuring out which antenna will work best for your location.

A superheterodyne receiver is a type of radio receiver that converts a high-frequency signal to a lower intermediate frequency (IF) for easier processing. It employs a mixer to combine the incoming radio frequency (RF) signal with a locally generated oscillator signal, producing the IF. This allows for improved selectivity and sensitivity through the use of filters and amplifiers. The basic components include an antenna, RF amplifier, mixer, local oscillator, IF amplifier, detector, and audio amplifier.

The basic components of a transmitter are; transistors, capacitors, resistors, condenser, Inductor, and antenna.

Reflection of a transmitted signal is the basic premise of radar and sonar.
purchase an FM mudulator. it wires to your antenna to give an input signal through an FM station(88.7 for example). i bought one at a car stereo shop.
An amplifier will amplify a signal. For example, the antenna in a radio will receive an extremely weak signal; before it can be converted to a sound, it must be amplified (made stronger), by a factor of several million. Of course, since you can't produce energy out of nothing, an amplifier doesn't actually produce the energy for the strong version of the signal - it requires a power supply.
A wireless transmission consists of at a minimum: input signal (the data or analog signal you wish to transmit), transmitter, 2 antennas, space (the final frontier) and a receiver/reproducer. This only makes one way transmission possible. You would need an additional: transmitter, receiver/reproducer and 2 antenna couplers (allows both a transmitter and receiver to use the same antenna) to have 2 way communication. A basic transmitter consists of a power source, a signal generator (oscillator), signal converter/amplifier, mixer (mixes the oscillator and amp signals to create the transmitted signal), output amplifier. a receiver is similar to a transmitter except instead of mixing the signal with the oscillator signal it removes the oscillator signal. Systems can be much more complicated depending on power needs (distance between antennas, frequency interference...) and application (encoder/decoder, security or digital conversion).
