Radio waves are electromagnetic waves, which consists of electric & magnetic fields. When they hit matter they exert forces on the charges of the atoms that make up the matter. Radio waves are usually pretty weak so when they hit most materials not much happens because the atomic charges are pretty firmly in place. However, in metals some of the atomic electrons are not firmly in place and will be easily moved by a radio wave. This is why antennas work. The radio wave causes currents in the antenna which can be sent to a circuit which can convert the currents into the information that was sent by the radio wave (TV & Radio), if it was carrying information.
What else can I help you with?
What does a radio need to pick up radio waves?
antenna
Will any radio antenna pick up ultrasound?
No, radio antennas only pick up electromagnetic waves. Ultrasound is mechanical pressure waves, you need a microphone to pick them up.
A device used to detect radio waves from space?
they use radio waves to pick up some what satellite images or existance of things in space
Can waves carry viruses?
Waves coming into a beach may carry human viruses but the risk is low. Radio waves received by a radio receiver will not carry viruses that you could catch. Wireless communication used by computers should not carry viruses if the communication (radio waves) system is properly set up.
How are sound waves converted into radio waves?
Sound waves would not ordinarily be converted INTO radio waves.Sound Waves can be used to modulate the radio waves.The radio frequency of a typical FM station is around 100MHz.The audio is used to vary the FM frequency by the range of audio waves, perhaps 100 Hz up to 12 kHz. So the 100MHz signal varies from 100 MHz ± (100 to 12kHz)
Is a rainbow made up of radio waves?
no, they are made up of light waves, similar to radio waves and both are in the same spectrum (the electromagnetic spectrum) but they have different wavelenghts.
Is radio waves made up of many different types of electromagnetic radiation?
No. Only of radio waves.
Is radio waves a compound word?
No, "radio waves" is not a compound word. It is a noun phrase made up of two separate words.
What does not affect matter as they travel through it.?
Electromagnetic waves do not affect matter as they travel through it. This includes light waves and radio waves, which can pass through materials without interacting with the particles that make up the material.
What is the electromagnetic spectrum made of?
The electromagnetic spectrum is made up of different types of electromagnetic waves, ranging from low-energy radio waves to high-energy gamma rays. These waves differ in their frequency and wavelength, and include familiar forms of light such as visible light, infrared, and ultraviolet radiation. Each type of wave has unique properties and interactions with matter.
How are radio waves related to photons?
Radio waves are a type of electromagnetic radiation that consists of photons. Photons are the smallest unit of light and carry energy. When radio waves are transmitted, they are made up of photons traveling through space, carrying information and energy.
What does a radio need to pick up radio waves?
antenna
What are transverse waves made up of?
Transverse waves are made up of oscillations that occur perpendicular to the direction of wave propagation. This means that the particles in the medium move up and down or side to side as the wave passes through. Examples of transverse waves include electromagnetic waves like light and radio waves.
Can radio waves pass through wood?
Yes, radio waves can pass through wood, although they may be weakened or absorbed depending on the density and thickness of the wood. This is because wood is mostly made up of non-metallic materials that are generally transparent to radio waves.
How can radio waves convers to electrical energy?
An antenna picks up radio waves and converts them to electrical current
Some waves that do not require a medium are what?
Electromagnetic waves, gravity waves.
What makes radio waves?
Aside from radio transmiters set up by humans. nearly every thing emenates high frequency radio waves.
