The electromagnetic waves were produced experimentally by Hertz in 1888 using hertz oscillator which were of wavelength 6m Jagdish Chander Bose in 1895 graduated these waves which were of wavelength 5mm to 25mm and in 1896 G Margoni established a wireless communication between two stations 50 km apart using electromagnetic wave the amplitude of electric field is 10V m The frequency of wave is 5x10 4 Hz The wave is propagating along Z axis 1 If Mo ands are the absolute permeability relative permeability absolute permittivity and relative permittivity of the medium then the velocity of electromagnetic wave in a medium is 1 1 b E a c Hoo 1 HEHE d ME Hoo 2 In electromagnetic wave the average energy density due to magnetic field is a 8 85x10 10Jm 3 b 4 42x10 0Jm 3 c 2 21x10 10Jm 3 d 6 63x10 10Jm 3 3 In electromagnetic wave the total average energy density is a 8 85x10 10Jm 3 b 4 42x10 10Jm
