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


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.


How were the pulsing radio waves from the discovered object detected?

The pulsing radio waves from the discovered object were detected using radio telescopes that can pick up and analyze radio signals emitted by celestial objects in space.


What is an equipment used to receive sound sent over air waves?

A radio receiver is commonly used to receive sound sent over airwaves. It can tune in to different radio frequencies to pick up sound signals broadcast by radio stations.


Can guitar amps pick up radio signals while being used?

Yes, guitar amps can pick up radio signals while being used due to electromagnetic interference.


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


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.


Can humans pick up radio signals?

No, humans cannot pick up radio signals naturally.


Can you smell EM waves?

No, electromagnetic waves such as radio waves, microwaves, and visible light are not able to be detected by the sense of smell because they do not have a scent. These waves are typically detected by instruments or devices designed to pick up their specific frequencies.


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)
