What is the height?
In general, the height is the distance from the bottomUp to the top, measured along a vertical line from bottom to top. However, this term has other meanings. In this article, let's talk about what height is in different spheres of science and life.
Height in daily life
In everyday life, we are used to usingword height in value, as we have already mentioned, the distance from the bottom to the top of any surface or plane. The distance, I must say, can be not only physical. So, for example, the height of the wall is quite a noticeable value, but the phrase "to achieve heights in your business" has a slightly different nature, although when we say this phrase, we still mean the distance a person passed from the beginner to the professional , although this distance can not be felt and measured. In this case, the height has a high level of development.
A height can also be called an elevated place.
Height in math
The term "height" we often hear in geometry, the height of the figure is one of its most important parameters. The height of the figure is the perpendicular dropped from the top of the figure to its base.
The height of a geometric figure is oftenIt is used in formulas to calculate its area. So, for example, to find the area of a triangle, you must multiply the height by the base and divide the resulting product in half.
For information on how to determine the height of a triangle, see How to find the height of a triangle.
Height in physics
In physics, altitude is one of the basic properties of sound. The height of sound is determined by the frequency of its impact on the tympanic membrane - the higher the frequency of oscillations, the higher the sound.
It is interesting that the quantitative estimation of the pitch of sound is based on the statistical processing of a huge number of data on the subjective perception of sound.
Height in geography
The concepts of absolute and relative heights are distinguished in geography.
Absolute height (altitude) is the distance froma specific point on the earth's surface to the average level of the ocean surface. The absolute height is the third coordinate of the point on the earth's surface, complementing the latitude and longitude and giving the most complete picture of the location of the object. If the absolute altitude lies above the mean ocean level, it is considered positive, otherwise the altitude is called negative.
The relative height is measured from the conditional level, which in a particular case is required to be taken as zero.
To determine the heights of objects in geography, a device is used, which is called the level, and the measurement procedure itself is leveling.
Flight Height
The altitude of the flight is the distance from a certain reference level to the aircraft, measured vertically. The height of the flight can be relative, true and absolute.
The relative altitude of the flight is measured fromthe aerodrome level, the highest relief point, or any other point chosen as a reference point for some reason. The true altitude is determined from the point directly below the hull of the aircraft. The absolute height is measured from the ocean level.
