From west to east the six standard time zones in Europe are: (UTC/GMT -1) Azores Time Zone. (UTC/GMT +0) Greenwich Mean Time Zone, Western European Time Zone and Irish Time Zone. (UTC/GMT +1) Central European Time Zone.
Mechanical waves transport energy. This energy propagates in the same direction as the wave. Any kind of wave (mechanical or electromagnetic) has a certain energy. Mechanical waves can be produced only in media which possess elasticity and inertia. A mechanical wave requires an initial energy input. Once this initial energy is added, the wave travels through the medium until all its energy is transferred. In contrast, electromagnetic waves require no medium, but can still travel through one.
A mechanical wave is a disturbance that pulsates through some form of medium: a solid, a liquid, or a gas, carrying the original, initiating energy from one place to another.There are three types of mechanical waves: transverse, longitudinal, and boundary.or a transverse waves, the amplitude is the distance that the wave displaces the medium. The number of waves passing through the medium over time is the waveâs frequency. The higher the frequency of a mechanical wave, the greater the energy it transmits.
