Transcript

  • 1. By : Yoga Wahyu Sasongko
  • 2. Electromagnetic waves are waves thatresult from changes in the magnetic fieldand electric field respectively, where thevibration direction of the electric fieldvector and the magnetic field vectorperpendicular to each other
  • 3. Maxwell theory "If changes in the magnetic field can generate an electric field, the opposite changes in electric field can produce magnetic fields" changes in magnetic flux Changes in the electric field
  • 4. characteristics of the wave elecromagnetic Changes in Electric and Magnetic Field occurs at the same time electromagnetic waves do not have a cargo E and B directions perpendicular to each other and both perpendicular to the direction of wave propagation Can experience reflection, refraction, interference, diffraction, polarization
  • 5. The propagation velocity of electromagnetic wave The rate of electromagnetic wave with the rate of the light in the vacum. However, the length of wave ang frequency of electromagnetic wave not the same as the light. The relationship betwen the wave and the frequance wave is as the following c=f C = The propagation velocity of electromagnetic wave (3 x 108 m/s)  = wave length (m) f = frequence (Hz)
  • 6. Exemple :A radio wave is emitted at a frequency of 15 x104 Hz .Determine the wavelength of the emitted!Answer : c  f . c  f 3 x108 m / s  15 x104 Hz   2000m
  • 7. _THANK YOU VERY MUCH
