Propagation of EM Waves in Atmosphere
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..

Sky waves are the AM radio waves, which are received after being reflected from the ionosphere. The propagation of radio wave signals from one point to another via reflection from ionosphere is known as sky wave propagation. The sky ..
Requisites of the medium to propagate mechanical waves
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..
Propagation of sound waves in air from a tuning fork
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. Sound waves are classified as longitudinal waves. Let us now see how sound ..
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 reflection had taken place from a surface located at a greater height, called the vi..
Experiment to show that sound waves (mechanical waves) require a material medium for its propagation
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..

..Propagation of Sound
A material medium is necessary for sound propagation - Ordinarily, we hear sound, transmitted through the air. Unlike light, sound cannot pass through vacuum. This was discovered in 1654 by Otto Von Guericke. Let an electric bell be enclosed within a bell jar which is placed over a disc. ..

Tutor Vista teachers were knowledgeable and good in explaining to kids with 100% correct answers.... Landon
I learned a lot with this tutor. she was great at explaining the basic of chemistry. I have no questions left for the day. But I have lot to know from my tutor
Explained things very well and made them easy to understand
The tutor really touched the right methods and formulas that would help me the most as well as a helpful practice sheet to test my knowledge of the subject. Great work!
