Electromagnetic Waves
Although you might not know it you’re constantly surrounded by thousands of electromagnetic waves every day. Sunlight and x-rays are only two types of electromagnetic waves, other types are: radio wave, infrared rays, ultra-violet rays and gamma rays
Nature of an electromagnetic wave
Electric and magnetic fields are not made up of matter. An electromagnetic wave consists of an electric and magnetic field and doesn’t need a medium to exist. They are the regions through which the push or pull of charged particles and magnets is exerted. The magnetic field and an electric field positioned at right angles to each other and to the direction of motion of the wave. Because of this they are transverse waves.
Production and Transmission of Electromagnetic Waves
The source of all electromagnetic waves is charge that is changing direction or speed.
The Electromagnetic Spectrum
Electromagnetic waves are arranged in order of wavelength and......
