Answer:The electromagnetic spectrum is the incredibly broad range over which the frequency of electromagnetic waves can fluctuate. All forms of electromagnetic radiation are included in this spectrum, which is arranged according to frequency (or, conversely, wavelength).Radio waves: 300 GHz, or less than 3 x 10^11 HzMicrowaves: 3 x 10^9 Hz to 3 x 10^11 HzInfrared: 3 x 10^11 Hz to 4.3 x 10^14 HzUltraviolet: 3 x 10^16 Hz to 7.5 x 10^14 HzX-rays: 3 x 10^16 Hz to 3 x 10^19 HzAdditionally:4.3 x 10^14 Hz to 7.5 x 10^14 Hz is the visible light frequency.More than 3 x 10^19 Hz are gamma rays.In conclusion, electromagnetic waves exist across a wide range of frequencies rather than having a single frequency. The frequency of an electromagnetic wave determines its type.
