We generate and detect radio waves for purposes of communication, cooking, and
scientific investigation, in the frequency range of roughly 30 KHz to 300 GHz,
corresponding to wavelengths between 10,000 meters and 1 millimeter.
Speed of the radio wave c = 3 x 108 m/s. Frequency f = 107 x 106 Hz. Wavelength lambda = c / f = (3 x 108) / (107 x 106) = 2,80 m
Frequency = (speed) / (wavelength) = (3 x 108) / (0.024) = 1.25 x 1010 Hz = 12,500 MHz.
The speed of light is 300,000,000 meters per second. Divide that by 30,000,000 hertz and you get 10 meters. The good old 10 meter band of ham radio fame.

62.5 MHz. 62,500,000 hertz. One Hertz equals one cycle per second.
For any wave, frequency x wavelength = speed (of the wave). In this case, convert the kHz to Hz, then divide the speed of light by this frequency. The speed of light should be in meters/second. The answer will be the wavelength in meters.
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 milesA radio wave with a wavelength of 10 miles has a frequency of (186,282 / 10) = 18,628 Hz.
ultrasonic wave is sound frequency
Wavelength = speed/frequency = 300,000,000/100,000,000 = 3 meters
The speed of every radio wave is 186,282 miles (299,792,458 meters) per second. When you multiply the frequency times the wavelength, that's the result. If it isn't, then you made a mistake somewhere.

The frequency of a radio wave compares to the frequency of the vibrating electrons that make it because the frequency of a radio wave is proportional to the frequency of the vibrating electrons that make it.
Radio waves are lower frequency.
2(frequency deviation+signal frequency)
Frequency (1/seconds) x Wave Length (meters) = Speed (meters/sec. or m/s)
100 MHz (near the middle of the commercial FM broadcast band)
Multiplication of wavelength and frequency is equal to velocity of the wave.It is a constant in a medium.So wavelength and frequency is indirectly propotinal.One should increase if other decrease to maintain the constant velocity.
The wavelength of a wave is calculated using the formula: Wavelength = speed of the wave divided by the frequency of the wave. For radio waves and other wireless signals as well as the speed a signal travels along a wire, the speed of the wave is approximately 299,792,458 meters per second (the speed of light).
