I'll give you the equation and you can do the math yourself.E=hv, where E is energy, h is Planck's constant, and v (really a Greek letter nu) is frequency.
Extremely low frequency (ELF) radio waves. They can have wavelengths of over 60,000 miles (100,000 km) and frequencies from 3 to 300 Hz.
Frequency = velocity of the wave / wavelength Frequency = 3 x 108 / 1.28 x 107 So v = 23.4375 Hz
The formula is frequency = Energy/h where h is Planck's Constant, 2/3 E-33.

The radio band is the least energetic section of the electromagnetic spectrum.
Extremely low frequency (ELF) radio waves. They can have wavelengths of over 60,000 miles (100,000 km) and frequencies from 3 to 300 Hz.
E = h * nuE = 6.626x10^-34 J-sec * 3x10^9/sec E = 2.2x10^25 J
Frequency = velocity of the wave / wavelength Frequency = 3 x 108 / 1.28 x 107 So v = 23.4375 Hz
The formula is frequency = Energy/h where h is Planck's Constant, 2/3 E-33.
frequency [Hz] = velocity[m/s] / wavelength [m] frequency [Hz] = 24 [m/s] / 3 [m] frequency = 8 [Hz]
5,000 km = roughly 3,107 miles
The frequency of x-ray in the range 30 petahertzto 30 exahertz (3 × 1016 Hz to 3 × 1019 Hz) and
Assuming you are reffering to electromagnetic radiation, i.e. light, the formula for this is simply frequency*wavelength = speed (in this case a constant, the speed of light). Then, frequency = (speed of light) / wavelength, speed of light ~= 3 * 10^8 meters / second, and wavelength = 9.3 mm = 9.3 * 10^-3 m. Therefore frequency ~= (3 * 10^8) / (9.3 * 10^-3) = 27.9 * 10^5 Hz = 2.79 MHz, where 1 Hz = 1 / seconds.
Frequency = 1/period1/7.5 x 10-3 = 1331/3 Hz = 2/15 KHz
