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…
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…
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…
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…
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…
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…
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…
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…
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…
In line communication there is a physical connection between source and destination. The wired connections between two points are known as transmission lines. The wires that are most popular for…
