An electromagnet uses

Arrange the given electromagnetic radiations in the descending order of their frequencies. Infarred, X-rays, ultraviolet and gamma rays.

Electromagnetic spectrum Electromagnetic waves are coupled time varying electric and magnetic fields, propagating in space, with the speed very close to that of light (3xx10^8 ms^-1) . An the orderly distribution and classification of electromagnetic waves according to their frequency or wavelength is called electromagnetic spectrum. electromagnetic waves inclued visible light, ultraviolet waves, infra red waves, X-rays, gamma-rays, microwaves and radiowaves. The electromagnetic waves used in surgery for detection of fractures, diseased organs, forensic matter like bullet, etc, are

Show that the wavelength of electromagnetic radiation is equal to the de-Broglie wavelength of its quantum (Photon).
