By altering the properties of space, a radio wave may be directed or reflected. Your average radio aerial does this, and a yagi aerial (typical TV antenna) also is configured to ignore signals from certain directions. [Thus giving a better signal-to-noise signal. ]
Once captured in a wire conductor, the radio wave may then be amplified, and rectified (detected) or otherwise processed.
Frequency Modulation (FM) changes radio wave frequency, normally used to correct atmospheric and relative motion changes to accurately recreate the original signal.
The quantum process is called 'Atomic Scattering'. Particles absorb signals and re-emit them (equivalent to electrons absorbing photons and remitting them - in QED).
The effect is Doppler Shift, where wavelength and frequency (subject to observer frame) are altered to maintain the (EM signal or 'light' speed) 'c'. Look up Bragg refraction, PMD, and Raman and Stokes / Anti Stokes (up and down shifted) scattering for more detail.

What else can I help you with?
What is changing in an AM radio wave?
As time passes, the amplitude of AM radio waves is intentionally changed in order to add information to the waves that can be read at a distance.
Waves used for broadcastig radio signals are called what?
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
How does a usb radio transmitter work?
Radio transmission occurs when sound or pictures are changed into waves and transmitted. Radio waves are then sent to receivers. The more powerful that a signal is, the further the signal will travel
What is the galaxy called that sends radio waves?
Quasars
What is a radio waves strength or intensity called?
Watts
Are electromagnetic waves that are felt as heat are called radio waves?
No, electromagnetic waves that are felt as heat are called infrared waves, not radio waves. Radio waves have lower frequencies and longer wavelengths than infrared waves.
What is the process of varying radio waves?
modulation

What waves are transverse that disturb electromagnetic fields?
x-rays
What are Electromagnetic waves used in broadcasting are called?
Electromagnetic waves used in broadcasting are called radio waves. They are used to transmit signals for radio, television, and communication systems.
Explain how a radio station modifies waves in order to carry information.?
A radio station uses a process called modulation to imprint information onto radio waves. This involves varying the properties of the radio wave, such as its amplitude, frequency, or phase, to encode the desired audio signal. The receiver then demodulates these modified waves to extract the original information.
Which radiation is longer micro waves and radio waves?
"Microwave" IS radio waves. They're called microwaveswhen their frequency is 3 GHz or higher.
How does a usb radio transmitter work?
Radio transmission occurs when sound or pictures are changed into waves and transmitted. Radio waves are then sent to receivers. The more powerful that a signal is, the further the signal will travel
What are radio waves called to detect subs called?
Sonar.
What electromagnetic waves have the smallest amount of energy?
Those are called radio waves.
What is the process of using radio waves and magnetism to produce images of tissues in the human body?
This process is called magnetic resonance imaging (MRI). MRI uses a strong magnetic field and radio waves to create detailed images of tissues inside the body. The hydrogen atoms in our bodies align with the magnetic field, and when radio waves are sent through the body, these atoms emit signals that are used to create the images.
