propagation of wave

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..

In an Earth environment, electromagnetic waves propagate in ways that depend not only on their own properties but also on those of the environment itself. Since the various methods of propagation depend largely on frequency therefore the complete electromagnetic spect..

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..

Even before Sir Edward Appleton's pioneering work in 1925, it had been suspected that ionization of the upper parts of the Earth's atmosphere played a part in tile propagation of radio waves, particularly at high frequencies. Experimental work by Appleton showed that the atmosp..

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 vi..

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..
