Origin of Electromagnetic Radiation

 Electromagnetic radiation refers to the waves of the electromagnetic field radiating through space, carrying electromagnetic radiant energy.It consists of radio waves, microwaves, infrared, visible light, uv light, X rays, and gamma rays.

1)Electromagnetic waves are produced by electrically charged particles that are undergoing acceleration and these waves can interact with another charged particles, exerting force on them itself. 

2) EM waves carry energy, momentum as well as angular momentum away from their source particle .

3) Electromagnetic radiations are associated with those EM waves that are free to radiate themselves without the  influence of the moving charges that produced them, because they have achieved minimum distance from those charges. 

4) Thus ,a wave carrying energy of charged particles forms a radiation.

Introduction

Image
Electromagnetic spectrum:     It is  range of frequencies of electromagnetic radiation and their corresponding wavelengths and energy of the photon.  Fig. Electromagnetic spectrum It covers electromagnetic waves within the frequency range from below 1 Hz to 10^25Hz and it corresponds to wavelengths from thousands of km down to a fraction of size of atomic nucleus.  The range of frequency is divided into various bands and each of having different names: I) Radio waves II) Microwaves III) Infrared IV) Visible light V) UV Light VI) X- Rays VII) Gamma Rays Each of these bands or waves have different properties and characteristics, in respect to origin , interaction , and their applications .  All the above waves can be seprated physically by a technique called spectroscopy .

Applications of Electromagnetic Radiations

  Gamma rays are primarily used for killing the bacteria and other microinsects in marshmallows &for sanitizing medical equipment X-rays are basically used for scanning the structures of bone images.  Ultraviolet light can be used to observe bees because flowers can stand-out visibly at the  frequency range of uv light Visible light is most important because it is used to view the world by humans Infrared light is used in laser metal cutting, night vision, and heat sensors and many more such appliances.  Microwave is used in radar, sonar techniques and specially in microwave ovens Radio waves are primarily used in radio, TV broadcasting.
