wavelength=velocity x frequency
wavelength=3x108 x 90.7x103
wavelength=272.1x1011
Wavelength = Speed of light/frequency Wavelength= 300'000'000/104'900'000 (FM 104.9 is frequency modulation 104.9 MHz) Wavelength=2.86 meters
Assuming a propogation speed of 3x108 m/s (approximate speed of light), a frequency of 106.5 MHz would have a wavelength of about 2.8 m.
The wavelength of a frequency is the propagation speed divided by the frequency. A wave of 146 MHz, with a propagation speed of 3x108 m/s (speed of light), has a wavelength of 3x108 divided by 146x106, or about 2 m.
49 MHz (mhz) is the main radio frequency of the signal that controls a radio-controlled (RC) car. I hope that answers your question. :)
30.000 to 87.975 MHZ
The frequency of a 150 meter radio wavelength can be calculated using the formula: frequency = speed of light / wavelength. For a 150 meter wavelength, the frequency would be approximately 2 MHz (megahertz).
The wavelength of a 99.0 MHz signal is about 9.94 feet.
Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
For 90.7 MHz: λ = about 10.84 feet.
The frequency can't be 30 Mhz 30 Mhz is a ham radio frequency but to calculate the wavelength, devide 300 by the frequency in Mhz that will give you 10 meters (300/ƒ)
300 MHz: λ = about 3.278 feet.

Wavelength = Speed of light/frequency Wavelength= 300'000'000/104'900'000 (FM 104.9 is frequency modulation 104.9 MHz) Wavelength=2.86 meters
Frequency = speed/wavelength = 299,792,458/2.5 = 119.917 MHz (rounded)If you use the popular, approximated and rounded value of 3 x 108m/sfor the speed of light and radio, then you get 120 MHz.
"Meters" is not frequency. It's wavelength. If you know the wavelength in meters, divide 300 by it, and the result is the frequency in MHz. If you know the frequency in MHz, divide 300 by it, and the result is the wavelength in meters.
Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
Frequency = speed/wavelength = 300,000,000/2 = 150,000,000 = 150 MHz. (The ham-radio band from 144 to 148 MHz is usually called the "two-meter band".)
