wave propagation through

The AM radio waves which propagate from one point to another following the surface of Earth are known as ground waves or surface waves. This type of propagation is called ground wave propagation or surface wave pr..

All the effects so far described hold true for microwave frequencies, but some are increased, and new ones are added. Atmospheric absorption and the effects of precipitation must be taken into account. So must the fact that at such short wavelengths, everything tends to happen very rapidly. Refrac..

Important Terms Used in the Study of Sky Wave Propagation - As the wave is refracted, it is bent down gradually rather than sharply. However, below the ionised layer, the incident and refracted rays follow paths that are exactly the same as they would have been if refl..

As the wave is refracted, it is bent down gradually rather than sharply. However, below the ionised layer, the incident and refracted rays follow paths that are exactly the same as they would have been if reflection had taken place from a surface located at a greater height, called ..

The medium must possess the following properties for the propagation of the waves: The medium should be able to return to its original condition after being disturbed, i.e., the medium must possess elasticity. The medium must be capable of storing energy. The frictional resistan..

Electric bell suspended inside an airtight glass bell jar An electric bell is suspended inside an airtight glass bell jar connected with a vacuum pump. As the electric bell circuit is completed, the sound is heard. Now if the air is slowly removed from the bell jar by using a vacuum pump, the i..

A wave motion, in which the particles of the medium oscillate about their mean positions in the direction of propagation of the wave, is called longitudinal wave..
