a mechanical wave

A mechanical wave is a periodic disturbance, which requires a material medium (solid, liquid or gas) for its propagation. These waves are also known as elastic waves because their propagation depends upon the elastic properties of the medium through which the..

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 resistance must be..

Depending upon their propagation in a medium, the waves are classified as follows: Mechanical waves or elastic waves and Electromagnetic waves..

Probability Picture of Electrons and Concept of Atomic Orbital (Wave Mechanical Treatment) - The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around t..

The wave character of an electron and uncertainty in its position and momentum gave a serious blow to Bohr's model of an atom. According to Bohr, the electrons revolve around the nucleus in certain well-defined circular orbits. But the idea of uncertainty in position and velocity ov..

In this, the patient lies down surrounded by massive electromagnets and is exposed to short bursts of powerful magnetic field and waves. These bursts stimulate the protons (hydrogen nuclei) of the patients tissues to emit radio signals which are picked up and converted into digital signa..

Mechanical waves - These are waves which require a material medium for their propagation and can be described using Newton's laws of motion. Examples: water waves, sound waves, seismic waves, and shock waves. Mechanical..

Electromagnetic waves returned to Earth by one of the layers of the ionosphere appear to have been reflected. In actual fact, the mechanism involved is refraction. As the ionisation density increases for a wave approaching the given layer at an angle, so the refractiv..

The sound waves are directed towards the ear canal by the pinna. The waves that enter the canal are concentrated and made to strike against the tympanu..
