The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.
Which answer arranges the form of electromagnetic energy in order of increasing wavelength?
They include visible light, radio waves, x-rays, infra red, ultraviolet, microwaves and gamma radiations. When these waves are arranged in a certain pattern e.g in the order of increasing frequency or wavelength then we get an electromagnetic spectrum.
