Waves are wave movements which, in the field of physics, propagate from one place to another through different types of media such as water, gases, solid elements as well as empty fields. One of the essential factors for waves to occur are the so-called disturbances of the system such as the untimely alteration of the physical properties of a system; These alterations can be generated naturally or artificially.
The waves are mainly characterized by the following factors:
- Amplitude: which represents the distance between a point until it reaches its maximum point, which is usually called the crest, this factor is related to the intensity since, based on this force, it reaches its highest point.
- Wavelength: this indicates the distance between 2 crests of a wave , this factor is also linked to the energy that the wave has but inversely, this means that the shorter the length the energy will be much more intense while that if the length is greater, this energy will be less intense.
- Frequency: this factor reflects the amount of oscillations that the wave has generated during a certain period of time.
- Period: is the period of time that the wave requires to make an oscillation.
- Propagation velocity: it is the distance that a wave travels per unit of time, in this case the value is based on the properties of the environment through which it passes, such as temperature, pressure and other factors.
There are electromagnetic waves which are electromagnetic radiations that cross space and are characterized by not having a specific physical medium. There are mechanical waves are alterations in tension that are expanded by physical means. In the same way, there are gravitational waves which are ripples that cross dimensions of space and time.
