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 radio waves travel through air?
Of course, they are similar to visible light waves, just a different wavelength and frequency. Indeed, many electromagnetic waves (radio waves) can travel through solid objects and water depending on the frequency and the medium through which they travel. If radio waves couldn't travel through the atmosphere, your radio wouldn't receive a signal, hence no music.
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)

How do telescopes pick up electro- magnetic waves in space?
-- They pick up light waves the same way telescopes, cameras, and your eyes do here on Earth. -- They pick up radio waves from the control center by means of antennas mounted under the optical assembly.
What is the difference between optical and radio?
Optical telescopes use either lens' (refractory) or mirrors (reflective) to magnify light. Radio telescopes use dishes to pick up radio waves. sensors on the dishes collect the waves and turn them into a picture

Is radio waves made up of many different types of electromagnetic radiation?
No. Only of radio waves.
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.
Which electromagnetic wave have the longest wavelengths?
The longest used is I think long wave radio which can be up to 1500 meters
What kind of electromagnetic has the longest wavelength?
The longest waves used regularly for communications are the VLF radio waves with a wavelength up to 30 kilometers.
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.
