For 90.7 MHz: λ = about 10.84 feet.
The wavelength of a 99.0 MHz signal is about 9.94 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)
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 = 300,000,000/2 = 150,000,000 = 150 MHz. (The ham-radio band from 144 to 148 MHz is usually called the "two-meter band".)
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.
