Conversion of units is the conversion between different units of measurement for the same . Name of unit, Symbol, Definition, Relation to SI units The technical definition of tropical year is the period of time for the ecliptic longitude of the. Menstruation is a natural process that is part of a woman's reproductive health. To learn why it happens and how it fits into the menstrual cycle. Two types of measurement systems are distinguished historically: an duration of Egyptian history, the weight of the kite varied from period to period, . relationship between different types of units, such as those of length and.
Period is a time quantity. As an example of the distinction and the relatedness of frequency and period, consider a woodpecker that drums upon a tree at a periodic rate. If the woodpecker drums upon a tree 2 times in one second, then the frequency is 2 Hz. Each drum must endure for one-half a second, so the period is 0. If the woodpecker drums upon a tree 4 times in one second, then the frequency is 4 Hz; each drum must endure for one-fourth a second, so the period is 0.
If the woodpecker drums upon a tree 5 times in one second, then the frequency is 5 Hz; each drum must endure for one-fifth a second, so the period is 0.
Do you observe the relationship? Mathematically, the period is the reciprocal of the frequency and vice versa.
Conversion Of Units
In equation form, this is expressed as follows. Since the symbol f is used for frequency and the symbol T is used for period, these equations are also expressed as: The quantity frequency is also confused with the quantity speed.
The speed of an object refers to how fast an object is moving and is usually expressed as the distance traveled per time of travel. For a wave, the speed is the distance traveled by a given point on the wave such as a crest in a given period of time.
So while wave frequency refers to the number of cycles occurring per second, wave speed refers to the meters traveled per second. A wave can vibrate back and forth very frequently, yet have a small speed; and a wave can vibrate back and forth with a low frequency, yet have a high speed.
Frequency and speed are distinctly different quantities. Wave speed will be discussed in more detail later in this lesson.

How do changes in the frequency of a wave affect the wavelength of a wave? Use the Wave plotter widget below to find out. Alter the frequency and observe how the pattern changes. We Would Like to Suggest Why just read about it and when you could be interacting with it?
Interact - that's exactly what you do when you use one of The Physics Classroom's Interactives. Important Terms Before we move ahead to the list of important mensuration formulas, we need to discuss some important terms that constitutes these mensuration formulas.

Area A — The surface occupied by a given closed shape is called its area. Perimeter P — The length of the boundary of a figure is called its perimeter. In other words, it is the continuous line along the periphery of the closed figure. Volume V — The space that is contained in a three-dimensional shape is called its volume.
In other words, it is actually the space that is enclosed in a 3D figure. Curved Surface Area CSA — In solid shapes where there is a curved surface, like a sphere or cylinder, the total area of these curved surfaces is the Curved Surface Area.
The acronym for this is CSA and it is measured in m2 or cm2. Lateral Surfaces are those surfaces that surround the object. The acronym for this is LSA and it is measured in m2 or cm2.

For example, in a cuboid when we add the area of all the six surfaces we get its Total Surface Area. The acronym for this is TSA and it is measured in m2 or cm2. When we measure the area of any surface we refer to this square of side one unit and how many such units can fit in the given figure.
It is expressed as m2 or cm2, depending on the unit in which the area is being measure. When we measure the volume of any figure we actually refer to this cube of side one unit and how many such unit cubes can fit in the given closed shape. It is written in m3 or cm3, depending on the unit that is being used to measure.
