v = f * lambda\n(where v is velocity, f is frequency and lambda is wavelength)\n\n:. lambda = v / f\nv = 3 * 10^8 m/s (speed of an electromagnetic wave)\nf = 88 MHz = 88000000 Hz\n\n:. lambda = 3*10^8 / 88000000\n                = 3.41 m\n\nie. the length of a typical radio wave is 3.41 m

Radio frequency, or RF, refers to that portion of the electromagnetic spectrum in which electromagnetic waves can be generated by alternating current fed to an antenna

MB is megabytes, a unit of storage space.  MH is nothing unless you mean MHz which is MegaHertz which is a unit of frequency.  In other words, apples and oranges

The RF waves emanating from an antenna are generated by the movement of electrical charges in the antenna. Electromagnetic waves can be characterized by a wavelength and a frequency. The wavelength is the distance covered by one complete cycle of the electromagnetic wave, while the frequency is the number of electromagnetic waves passing a given point in one second. The frequency of an RF signal is usually expressed in terms of a unit called the "hertz" (abbreviated "Hz"). One Hz equals one cycle per second. One megahertz ("MHz") equals one million cycles per second.

wavelength = speed/freqency \n=> (3 x 10^8)/(10^15)\nSo that is 3 x 10^-7 m\nor 3000 angstrom

maxwell eqn \nther is no need to rember  it 's of no use\n till you pass out of school\nbandwidth it's the range of length within \nwhich any elctromagnetic wave may fall or lie in like the bandwidth for visible light 400 nanometers to 700 nanometers

Exactly 299,792,458 meters per second (m/s). I say exactly because at one point the official length of a meter was modified slightly to make c come out to a even number of meters per second, rather than having some annoying decimal places.\n\nStill, most people prefer to round up to 300,000,000 m/s.

We've usually got about 36 hours warning of solar flare problems.   The light only takes about 8 minutes to reach us, but the charged particles that disrupt the ionosphere take around 36 hours, and both are produced simultaneously.   It's short wave radio that is affected.   For long distance communication around the curve of the Earth you use short waves in the frequency range 3 to 30 MHz. These are bounced around the world between the ground and layers of charged particles in the ionosphere about 100 km up.   The solar storm particles damage this reflective layer temporarily, sothe short waves shoot out into space.

Marconi transmitted the first radio waves that contained information in about the year 1895.  Those radio waves today would have traveled 111 light years, since radio wave travel at the speed of light.  They were not very strong and they may not be distinguisable from the background radiation but they are out there traveling outward from the point in space where they originated. \n\nNow you might as ask how far is 111 light years.  On an astronomical scale, not very far.   The Milky Way galaxy is about 80,000 to 100,000 light years in diameter.  So our first radio waves have traveled only 0.0014 % of the distance from one end of the galaxy to the other.  The Sun is about 26,000 light years from the center of the galaxy so the first radio waves have traveled only 0.0043% of the way to the center. \n\nThe nearest star to the sun is 4.4 light years away.  The 50 closest stars are within 15 light years.  The 100 nearest are within 30 light years.  So it is likely that the first radio waves have reached about 400 to 500 stars in the galaxy by now.  Let's put that into some perspective.  The galaxy is estimated to contain 200 to 400 billion stars. \n\nThe next nearest large galaxy is Andromeda galaxy.  It is 2.5 million light years away.  It is quite probable that by the time the first human radio waves reach Andromeda, humans may no longer inhabit the universe.

Frequency is measured in Hertz, or inverse seconds.  So take the inverse of 6, which would be 1/6, which is your frequency.  Tada!

the lowest frequency, like low-band radio has a wavelength of about 2-300ft, but theoretically if you could produce EM waves at frequencies much lower then that, you could get wavelenghts of even light years in length, but that's not very practical to do, i doubt if its even possible.
