Explain the atmosphere of earth in respect of Communication?
admin The envelope made up of gases which is surrounding our earth is known as atmosphere. There are lot of gases which combine together to form the atmosphere. The major composition…
Explain the behavior of atmosphere towards infrared radiations and infrared light?
The atmosphere shows variation in behavior for different types of radiations. The sun and the stars present in our atmosphere are clearly visible to us. This is due to the…
What are the major advantages of the ozone layer?
The major function of the ozone layer is to stop the harmful radiations coming from the sun as well as from stars. Ozone captures those radiations which are of low…
What are Radio Waves?
Those waves which have a frequency range of few kilo hertz to few hundred mega hertz are known as radio waves. The most common frequencies which are used by the…
How electromagnetic waves propagate in Atmosphere?
The magnetic field and electric field oscillations perpendicular to each other or in the direction same as that of the wave propagation as basically known as Electromagnetic waves. The nature…
What is space wave propagation?
The radio waves having high frequencies are basically called as space waves. These waves have the ability to propagate through atmosphere, from transmitter antenna to receiver antenna. These waves can…
What is Microwave Propagation?
Electromagnetic waves having frequency greater than that of the television signals are known as Microwaves. These waves have very less wavelength nearly few millimeters. Due to their low wavelength, these…
What is Remote Sensing?
To measure the characteristics of an object from a distance, the technique of remote sensing is used. By this technique we can collect all information about an object without making…
Explain the different losses in Transmission lines?
The energy losses that happen in case of transmission lines are shown below: 1. Conductor Heating 2. Dielectric heating 3. Radiation Losses It is observed that the radiation loss in…
What is Satellite Communication?
In satellite communication, signal transferring between the sender and receiver is done with the help of satellite. In this process, the signal which is basically a beam of modulated microwaves…
