The correct answer is: \( G, X, U, V, I, M \) and \( R \)

The electromagnetic (EM) spectrum is the range of all types of EM radiation. The γray has a maximum frequency or minimum wavelength; since the wavelength is inversely proportional to frequency, while radio wave has a minimum frequency and maximum wavelength. The order of wavelength will be; Gamma rays G < X-rays X < Ultra violet U < Visible rays V < Infrared rays I < Microwaves  M < Radio waves R.
