With the digits written in the question, the unit should be "meters per second", not miles.
A radio wave with a wavelength of 10 meters has a frequency of (300,000,000 / 10) = 30 MHz.
300,000,000 meters = 186,282 miles
A radio wave with a wavelength of 10 miles has a frequency of (186,282 / 10) = 18,628 Hz.

Component of electromagnetic waves that does not vary?
-- Frequency -- Wavelength. -- Speed. While each of these may vary their inter-relationship does not. Frequency - V Wavelength -L Speed - c VL=c is always true. c= varies depending on the medium through which the light is propagated.
In what ways are sound waves and electromagnetic waves similar?
they both have wavelenghth and have energy
How does the wavelength of a G-note sound wave compare to the wavelength of an A-note sound wave?
Assuming that both notes are in the range of C4 (middle C) and C5, G has a frequency of 392Hz, and A has a frequency of 440Hz. Assuming that both sound waves are travelling through air, through which sound travels at 340ms-1, then the wavelengths for G and A can be found to be 0.87m and 0.77m, respectively.An easier way to assess a change in wavelength would be to look at the equation v=fλ, where v is the speed of sound, f is the frequency of the note, and λ is the wavelength of the note. A higher pitch note means a higher frequency, and since the speed of sound is constant, then if the pitch is increased the wavelength must compensate by decreasing.Simply put, higher pitch means smaller wavelength.
What is the sped of radio waves through a vacuum?
v=f^ where v is velocity f is frequency ^ is (suppose to be the symbol of lambda but im to lazy to pull it from character map) wavelength of waves this formula applies for radio waves in vacuum so v(speed) is frequency of the radio waves multiplied its wavelength
What is the wavelength of the FM radio station 91.50 FM?
Wavelength = speed/frequency299,792,458 meters per second/94,400,000 per second = 3.176 meters = 10ft 5in(For the speed, I used the speed of light/radio in vacuum, although you actuallyreceive your FM program through air. The speed of radio is very slightly less inair, and that implies a very slightly larger wavelength ... less than a small fractionof a hill of beans.)
If a vacuum has a frequency of 1.01000000000000000000 what is the wave length?
Vacuums don't have frequencies.Electromagnetic waves moving through vacuums have frequencies and wavelengths.They also have speed. Regardless of their frequency and wavelength, their speed is always299,792,458 meters per second.The wavelength of an electromagnetic wave is [ (its speed) divided by (its frequency) ].If its frequency is 1.01 Hz, then its wavelength is 296,824,215.8 meters (about 184,438 miles).
What is energy that can travel through empty space?
Electromagnetic radiation can travel through "empty" space. Depending on the wavelength of the electromagnetic radiation, we call it "radio" or "microwaves" or "heat" or "light" or "UV" or "X-rays" or even "cosmic rays" - it's all different frequencies of EM radiation. The shorter the wavelength, the higher the frequency; in fact, the frequency times the wavelength is the constant "c", the speed of light.
If a sound wave and an electromagnetic wave have the same frequency which has the longer wavelength?
Wavelength is inversely proportional to frequency, but it is directly proportional to the velocity of propagation. Since sound propagates through air much more slowly than EM waves propagate through the atmosphere or the vacuum of space, the wavelengths of sound waves are much smaller for identical frequencies.

A certain wave has a wavelength of 45.0 meters and a frequency of 9.00 Hz What is the speed of the wave?
The speed of propagation of an electromagnetic wave (like light, which is an electromagnetic wave) is nearly the speed of light. It will actually be the speed of light in a vacuum. But it does travel a little more slowly depending on the medium through which it is traveling. (Like air.) The frequency of the electromagnetic wave is not a determining factor in finding its speed, but will certainly be a factor in determining its absorption by the medium. A radio wave of 9.5109 Hz is a really low frequency wave, and generating and transmitting it would be a pretty piece of engineering.
What is the wavelength associated with a frequency of 2.06 x 1014 hz?
The wavelength is (speed of the wave) / 2.06 x 1014 .If the wave is an electromagnetic one propagating through vacuum,then the wavelength is3 x 108 / 2.06 x 1014 = 0.001456 millimeter = 1,456 nanometer (rounded)
What is the equation for wavelength?
The formula for wavelength λ = v/f where v is the velocity f is the frequency of the wave and λ (lambda) is the symbol for wavelength Wavelength formulaC=λf or λ=C/f
Which wave in the EM spectrum has the shortest wavelength?
Gamma rays have the shortest wavelength. Electromagnetic wave is a kind of energy being propagated even through free space (vacuum). It is classified based on the mode of producing it as Radio waves, micro waves, infra red, visible, ultra violet, X-ray and Gamma ray. Out of these seven, radio waves have the lowest frequency and Gamma ray has the highest frequency. As frequency and wavelength are inversely related, radio wave would have the longest wavelength.
In what ways are sound waves and electromagnetic waves similar?

What can tell about the speed of two waves that have the same wavelength and frequency?
IF they're both mechanical waves or both electromagnetic waves, AND they'reboth moving through the same stuff, THEN they both have the same speed.

When a wave is passing through a uniform medium and the frequency of this wave increases it wavelength does what?
The wavelength gets longer.
