Electromagnetic wave is wave type moving without relying on the medium. Based on the inductance between the magnetic field and electric field which changes all the time.
.The study also shows that the electromagnetic wave frequency range is unique, it is called differently. When the order from low frequency to high frequency is as follows: Radio, microwave, infrared radiation, แสงที่ตามองเห็น.X-rays and gamma rays, the electromagnetic frequency range with every consecutive include called electromagnetic spectrum. Electromagnetic spectrum)
.
.Electromagnetic spectrum refers to electromagnetic waves whose frequency continuousness from minimum to maximum frequency, it is found that the spectrum of electromagnetic radiation is known as sources and different detection methods.Is
.1. Features reflection refraction, interference, diffraction, and treasure is polarization
2.? The speed of light is 3 x 108 M / S
3.The energy transmitted along with the wave. Which this energy will depend on the frequency and wave length by considering the photon energy.
