E = hf
The energy per photon is equal to Planck's constant times the frequency, in this case 6.62606957×10−34 x 107.3x106

How can the sun cause disruptions of radio signal?
The Sun generates electromagnetic energy in every frequency as it fuses hydrogen to helium in its core. Electromagnetic energy is, depending on the frequency, light, heat, radio, X-rays, gamma rays, and everything in between. So the Sun is continually generating radio energy and radiating it out in all directions. We can receive those radio signals from the Sun and other stars; that's the basics of how "radio telescopes" work. But sometimes, the radio signals from the Sun can interfere with the radio signals that we ourselves generate, and this can cause disruptions in our own signals. This can especially be an issue when the Sun has emitted a "Coronal Mass Ejection" which strikes the Earth, causing a "solar storm".
What does FM stand for in radio frequency?
FM means Frequency Modulated.FM stands for modulation on frequency or frequency modulation.
What are 3 forms of Electromagnetic Radiation with a wavelength less than visible light?
The wavelength of electromagnetic radiation is a measure of the frequency; multiply the frequency times the wavelength, and the answer is ALWAYS the "Speed of Light", which we abbreviate as "c". All of these are different "bands" of electromagnetic energy. Radio is the longest wavelength and lowest frequency. "Low Frequency" is the lowest, followed by "high frequency", "very high frequency" or VHF, "ultra-high frequency" or UHF. Beyond that are microwaves, and then heat, then "infrared", and then visible light. Higher frequency (and shorter wavelengths) than light are "ultra-violet", then X-rays, and then "gamma rays".
What radios contain intermediate frequency transformers?
AM (amplified modulation) radio contain the intermediate frequency transformer.it has IF to mixed the carrier signal into local oscillator signal in a process called heterodyning, resulting in a signal at the difference or beat frequency. Intermediate frequency are used in superheterodyne radio recievers, in which an incoming signals is shifted to an IF for amplication before final destination is done.
Does a frequency counter help a cb radio that much?
For CB's that are both modern and "legal" a frequency counter does not help much at all. However if you have an older radio with continuous tuning (dial with a needle) or are tuning "out of band" (using an illegal modified CB) you may find a frequency counter very useful. No,All the frequency counter does is match the frequency to the radio, to tell you how accurate the radio is, if it is a quality radio it is a waste of time for a more efficent CB radio you would want a RF meter to match the antenna to the radio, this would give you max signal when you key the mike, most of the radios that I have ever used have a signal strength right on the radio. All radios are designed to reject all frequencies except the one it's tuned to. Transmitter accuracy and receiver accuracy are both important for clear reception. CB radio uses 26-27 Mhz with a channel spacing of only 10Khz. If your transmitter's frequency is 5Khz too high and the person you're trying to talk to has a receiver that is a few Khz too low, you may not be able to talk to them at all or the sound will be distorted. All radios can be aligned. Better quality radios will not necessarily hold that alignment better. Antenna matching will affect how strong the signal is but not the frequency accuracy of that signal. A frequency counter will tell you what frequency you are on. It does not help the average CB radio. But it does do a lot for modified cb's with extra channels. A Frequency counter also comes in handy if you are talking on side band, it helps you remember where to set the dial, and makes tuning someones signal in much easier. A Frequency counter will help if you need it. If you dont need it it is a waste of money. ~TeZ~
Do radio waves have more energy then microwaves?
Nope. Radio waves have a long wavelength, which causes them to carry little energy. For future questions about energy and waves, use the formula E=h(c/lambda). E is the energy of the wave, h is plank's constant, c is the speed of light (3x10^8), and lambda is the frequency. Have fun! ^_^
Which type of electromagnetic wave has less energy than an infrared wave?
Waves with lower frequency: for example radio waves.
Which em spectrum has the longest to the shortest energy?
There is no such thing as "long energy" or "short energy". The electromagnetic spectrum is:Radio waves; microwaves; infrared; visible light; ultraviolet; x-rays; gamma rays. In this list, going from left to right: * The energy per photon increases. * The frequency increases. * The wavelength decreases. Thus, for instance, gamma rays have the LARGEST energy per photon; the LARGEST frequency; and the SHORTEST wavelength.
Which wave has more energy out of microwaves radio waves infrared waves and visible light waves?
The radio spectrum for communications spans approximately from 150 kHz to 26 MHz. The visible light frequency range is at least 400 THz. No contest -- visible light is at least 15 million times higher in frequency. Energy = Planck's constant * frequency. Hence visible light carries a higher energy.
What is the difference between light energy and radio wave energy?
Visible light and radio waves are both two types of the same radiation (electromagnetic waves). The difference is that visible light has a higher frequency; a higher energy per photon; and a smaller wavelength.
Is a red light photon a higher energy than a radio photon?
he duble hockey sticks no.
What is the difference among radio waves and other parts of the electromagnetic spectrum?
Their wavelength (or frequency), the energy carried by each photon, and the names we give them. Their speeds are all the same.
How do the waves of the electromagnetic spectrum differ?
In the spectrum of electromagnetic radiation the wave property that changes is the frequency. So for example xrays have higher frequency then blue light which has higher frequency then red light which has higher frequency then radio waves etc.
A low energy electromagnetic wave would also have?
the lowest frequency Lester was here

Relate energy of radio to frequency of wave?
Energy of radio signal E = hf, Planck's constant times the frequency.
