Electromagnetic waves in a vacuum move at the speed of light in a vacuum, as light is just one form of electromagnetic wave. According to Einstein's Theory of Relativity, nothing can move faster than the speed of light in a vacuum, so there is no way to speed up radio waves (unless they are initially moving in some other medium than a vacuum).

Why do you need a carrier wave?
In radio transmission, you could theoretically transmit radio signals at audio frequencies. However, because the wavelength of electromagnetism at audio-like frequencies is Huge and the frequency of a radio transmitter dictates the size of the antenna and the power requirement, you would need A Very Big Antenna and a Very Big Power Supply to do this. So, we've learned to transmit at higher "carrier" frequencies, modulating either the amplitude or frequency of the carrier signal with our audio and subtracting the carrier at the receiver end.
On a Motorola portable radio what is the difference between channel and frequency?
Not only on Motorola Portable radio, but in all radio communications: Frequency is number of cycles (full change circles) per second. When radio device operates on some frequency it requires band of adjacent frequencies to be able to transmit modulation (information) too. To avoid mixing, next transmitter must take some "distance" (higher or lower frequency) far enough from frequency of the first one. According to regulations basic frequencies are "named". Channel number is the name of its frequency given by communication regulations. For example, TV UHF channel 21 takes all frequencies from 512 to 518 MHz (megahertz), channel 22 from 518 to 524 MHz, and so on... CB Radio channels 21 and 22 occupy frequencies from CB band, not from TV band. Tables of channel frequencies within various bands can be easily found by search engines.
H parameter operate in which frequency?
up to radio frequencies i.e 20-20kh
How do you stop a satellite signal in a temple?
Microwave Radio Frequencies (RF) does not travel through dense metals. A metal roof would block the signal. If you try to get your position on a GPS inside the temple and cannot, then the satellite signals are blocked.
What does a communication system analyzer do?
Check the radio on sensitivity,power,capability on receiving frequencies, and to check if it's weak or not.
Which has a higher frequencies am radio waves or fm radio waves?
FM radio has the higher frequency which is why it sounds better. AM is a lower frequency but can travel further because the waves bounce off
What are the advantages of larger radio frequencies over smaller ones?
easier to transmit, higher frequencies radiate better. there is more bandwidth available at higher frequencies. higher frequencies travel in straighter lines so are more directional, this may or may not be an advantage depending on what is needed
Gamma rays faster than radio waves?
No. Gamma rays and radio waves are both electromagnetic waves and travel at the same speed. They just have different wavelengths/frequencies.
What is the plural of frequency?
The plural of frequency is frequencies. As in "radio waves travel on different frequencies".
Do visible light waves have higher frequencies than radio waves?
Yes, visible light waves have higher frequencies than radio waves. Visible light waves fall within the range of frequencies on the electromagnetic spectrum that is higher than radio waves.
What wave viabrates faster radio wave or microwaves?
Microwaves ARE radio waves, with frequencies above 3 GHz.
Is light part of the radio spectrum?
No, light is not part of the radio spectrum. But, both the radio spectrum and light are part of the electromagnetic spectrum. The electromagnetic spectrum is a range of frequencies from very low to very high. Light frequencies are higher than radio frequencies but both are the same kind of thing.
Does a radio wave or gamma ray have higher a amplitude?
A gamma ray has a higher amplitude than a radio wave. Gamma rays have shorter wavelengths and higher frequencies compared to radio waves, resulting in higher energy and therefore higher amplitudes.
Which radio show wakes up Snorlax?
Pokeflute the channel is found on the higher frequencies.
Is determined by the medium wave?
The determination of the medium wave frequency range is between AM and FM radio frequencies. Medium waves have lower frequencies than FM but higher frequencies than long waves. They are commonly used for AM radio broadcasting.
Is the following sentence True or false microwave are the radio waves with the shortest wavelengths and highest frequencies?
True. Microwaves have shorter wavelengths and higher frequencies compared to radio waves, falling between infrared radiation and radio waves on the electromagnetic spectrum.
What is the frequency of radio wave?
Fm radio waves travel at various frequencies between 87.5 MHz and 108.0 MHz
