If microwaves, X ‐ rays, infrared, gamma rays, ultraviolet, radio...

The electromagnetic (EM) spectrum is the range of all types of EM radiation. The $\gamma ‐$ray 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 $R$.
