  answer:

  Radio waves are a type of electromagnetic (EM) radiation with wavelengths in the electromagnetic spectrum longer than infrared light. They have have frequencies from 300 GHz to as low as 3 kHz, and corresponding wavelengths from 1 millimeter to 100 kilometers.

  high frequency

  Explanation:

  because the high frequency has a wavelength range of 10m-100m

  The frequency of radio waves with a wavelength of 20m is

  1.5 e+7 Hertz (Hz) or 15 million Hertz.

  This was obtained from the formula speed (c) is equal to the product of frequency (f) and wavelength (λ)

  c = fλ  

  Since we are looking for the frequency, we will divide both sides of the formula above by the lamda symbol for wavelength, which gives us:

  f = c / λ

  The value of wavelength is already given which is 20 meters. The speed of radio waves is the same with the speed of light when travelling in a vacuum – also with the other electromagnetic waves. Hence the speed (c) is 3 e+8 m/s

  f = 3 e+8 m/s   /    20m

  f = 1.5 e+7 Hz

  Just the radio waves has high frequency and it is the lowest wavelength..
