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.
FM signals travel as what changes?
FM signals travel as changes in the frequency of the wave.ANSWER: DEFINITELY not frequency remains the same.The duty cycle changes.It definitely IS the the frequency which changes. It changes at the same rate as the frequency of the modulation.It can be demodulated with a frequency discriminator. If the frequency remained constant and its "duty cycle" changed, the discriminator wouldn't demodulate it.
Does a radio wave travel faster than a sound wave?
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
Why are radio signals not transmitted directly by electromagnetic waves?
The question's meaning is mysterious. Radio signals AREelectromagnetic waves,specifically those in the band of frequencies/wavelengths known as "radio waves".That's exactly what is physically transmitted. Between the transmitting antennaand the receiving antenna, the energy of the radio signal, and the informationencoded in it, travels in the form of electromagnetic waves.
What do radio waves travel easily through?
Air
How do signals travel in space?
By use of electromagnetic waves, usually microwaves or radio waves.
Can gps signals travel underwater?
No. The GPS signal is high-frequency radio waves. High frequency radio waves cannot travel through water.
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.
Why do radio waves travel faster than the sound wave?
Radio waves are just low frequency light waves. They travel at the speed of light, much faster than sound waves which are just changes in pressure traveling in waves
How are radio waves and television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.
Cell phone signals are transmitted by?
radio waves radiation
Which waves carries AM and FM signals?
Radio waves
What travel faster a radio signal or sound in air explain?
Radio signals travel at (essentially) the speed of light, as they are electromagnetic waves like light. Sound waves travel at roughly 1200 km/h. Now you have enough information to answer your own question.
How are radio television signals added to EM radio waves?
by changing the amplitude or frequency of the radio waves.

It changes at the same rate as the frequency of the modulation.It can be demodulated with a frequency discriminator.

What do baby monitors have to do with Electromagnetic waves?
The monitoring device is a radio transmitter that sends signals to the radio transmitter. Radio waves are a type of Electromagnetic waves.
Which EM waves can carry television signals?
Radio waves. Low frequency.
