10 meters
Radio is a portion of the electromagnetic spectrum, as is visible light. The wavelength (Greek letter lambda) can be calcualted from the frequency (f) by the formula, lambda = c/f, where c is the speed of light or 2.998 x 108 m/s.
Here is the calculation ( the unit Hz = 1/s)
c = (3 x 10^8 m/s) / (3 x 10^7 1/s)
c = 10 m

What is the frequency of a electromagnetic wave with a wave length of 12800 KM?
Frequency = velocity of the wave / wavelength Frequency = 3 x 108 / 1.28 x 107 So v = 23.4375 Hz
What is the wavelength of an electromagnetic wave that travels at 3 x 108 and has a frequency of 60 MHz?
Wavelength = (speed) divided by (frequency) = (3 x 108) / (6 x 107) = 5 meters
What is the wavelength of radio waves emitted at 81.6 MHz when the speed of all electromagnetic waves in empty space is 3.00 x 1000000000 meters per second?
wavelength = velocity / frequency > = 3 * 108 metres per sec / 8.16 * 107 hertz > = 3.676 metres
What wavelength should the astrophysicist look for to detect a transition of an electron from the n equals 7 to the n equals 3 level?
, Use Rydberg's Equation to solve for this problem, which is as follows: 1/wavelength = R((1/n2x )-(1/ny2 )) Where R is Rydberg's constant, 1.0974 * 107 m-1 And where nx is the lower energy state (n=1), and ny is the higher energy state (n=3). So, plugging in those values gives us the following calculations to be made: 1/(12)=1, and 1/(32)= 1/9, so (1) - (1/9) = 8/9. So, we get: 1/wavelength = (1.0974* 107 m-1)(8/9) = 1/wavelength = (.9754666667 m-1) = wavelength = 1/(.9754666667 m-1) = Wavelength = 1.025150355 * 10-7 m And, since wavelength is typically given in nanometers (1 nm = 1 * 10-9 m) when looking at hydrogren emission spectra, convert the 10-7to 10-9 by moving the decimal back two more places. So, The wavelength expected for light composed of photons produced by an n=3 to n=1 transition in a hydrogen atom is: 102.5150355 nm or, to three significant figures, 103 nm Hope I helped! I am an engineering student at the University of Arizona.
What is the approximate energy of a photon having a frequency of a 4 x 107?
E = h x nu = 6.626176 x 10-34 joule-seconds x 4x10^7 sec = 2.65x10^-26 Joules
What is the frequency of a electromagnetic wave with a wave length of 12800 KM?
Frequency = velocity of the wave / wavelength Frequency = 3 x 108 / 1.28 x 107 So v = 23.4375 Hz
What is the wavelength of a radio station with a signal of 95.5 MHz?
speed of light = wavelength * frequence speed of light = 3*10 8th power
What is the wavelength of an electromagnetic wave that travels at 3 x 108 and has a frequency of 60 MHz?
Wavelength = (speed) divided by (frequency) = (3 x 108) / (6 x 107) = 5 meters
What is the frequency of a wave that has a wavelength of 3.55 meters The answer should only have 3 sig figs though. Someone please help me out?
The frequency is (speed of the wave)/(3.55 x 10-8) .Note:In order for this formula to work, the speed of the wave must be expressedin the same units as the wavelength, which the question doesn't specify.
What is the frequency of a radio wave that has a wavelegth of 4.8 meters?
We generate and detect radio waves for purposes of communication, cooking, andscientific investigation, in the frequency range of roughly 30 KHz to 300 GHz,corresponding to wavelengths between 10,000 meters and 1 millimeter.

wavelength = velocity / frequency > = 3 * 108 metres per sec / 8.16 * 107 hertz > = 3.676 metres
How long would it take a radio wave with a frequency of 7.75 multiplied by 102 Hz to travel from Mars to Earth if the distance between the two planets is approximately 8.00 multiplied by 107 km?
In free space a radio wave travels at about 300,000 kilometers per second. The speed doesn't depend on frequency. The distance of Earth from Mars is variable. I presume the question means a distance of 8.00 x 107 kilometers. So, the answer is about 80,000,000/300,000 seconds. That's about 800/3 = about 267 seconds. That's about 4 minutes and 27 seconds.
How communication devices work?
Sound and radio waves are different phenomena. Sound consists of pressure variations in matter, such as air or water. Sound will not travel through a vacuum. Radio waves, like visible light, infrared, ultraviolet, X-rays and gamma rays, are electromagnetic waves that do travel through a vacuum. When you turn on a radio you hear sounds because the transmitter at the radio station has converted the sound waves into electromagnetic waves, which are then encoded onto an electromagnetic wave in the radio frequency range (generally in the range of 500-1600 kHz for AM stations, or 86-107 MHz for FM stations). Radio electromagnetic waves are used because they can travel very large distances through the atmosphere without being greatly attenuated due to scattering or absorption. Your radio receives the radio waves, decodes this information, and uses a speaker to change it back into a sound wave. An animated illustration of this process is given below (mouse-over the images for animations).A sound wave is produced with a frequency of 5 Hz - 20 kHz.The sound wave is equivalent to a pressure wave traveling through the air.A microphone converts the sound wave into an electrical signal.The electrical wave traveling through the microphone wire is analogous to the original sound wave.The electrical wave is used to encode or modulate a high-frequency "carrier" radio wave. The carrier wave itself does not include any of the sound information until it has been modulated.The carrier wave can either be amplitude modulated (AM, top) by the electrical signal, or frequency modulated (FM, bottom).-ForonesThe signal is transmitted by a radio broadcast tower.Your radio contains an antenna to detect the transmitted signal, a tuner to pick out the desired frequency, a demodulator to extract the original sound wave from the transmitted signal, and an amplifier which sends the signal to the speakers. The speakers convert the electrical signal into physical vibrations (sound).
