what is relative frequency

Let u be the frequency of a wave. That is, the number of vibrations completed by a particle in one second is u . Time taken to complete u vibrations = 1 second. . But time taken to complete one vibration is defined as the time period of the wa..

Intensity of sound depends on its frequency. The human ear is more sensitive to the middle part of the audible range. Thus, a sound of a frequency in the middle of the audible range will appear to be louder than the sound of a frequency near the extremities of the ran..

If A and B are two non-empty sets, then a relation R in A x B is a subset of A x B. If we use the letter R to denote a relation, then we can write the relation between a and b as aRb a is related to b..

A relation R is a non-empty sub-set of a cartesian product. A relation is a set of ordered pairs, i.e., R A x B where A and B are two non-empty set..

Consider the following sentences:Consider the following sentences: 42 is a multiple of 6. Line l is parallel to line m. 10 is greater than 7. In each case the first element is related to the last element by the relation in italics. The two elements named are members of two separ..

The words who, which, where and whose are called relatives which give us information about a person or thing and help us to convey two-different ideas in a well-connected wa..

Which of the following statement(s) is/are false? I. Data such as blood types (A, B, AB, O) can be organised into a categorical frequency distribution. II. Except for rounding errors, relative frequencies should add up to 100. III. A statistical device used in explorat..

The number which tells us how many times a particular data appears is called the frequency. For example, 2 marks have been scored by five students which means marks 2 occurs five times. Therefore, the frequency of score 2 is five. Similarly, the frequency of mark..

In frequency modulation, the frequency of the carrier wave is modified in accordance with the amplitude of the modulating wave. The amplitude of the carrier remains unchanged at all times. In other words, the amplitude of the modulated wave remains the same as the amplitude of t..

The number of oscillations of a particle executing SHM in one second is called the frequency. It is the reciprocal of the period i.e., n = 1/T. It will be equal to the number of revolutions completed per second by the body on the circle of reference. Its unit is cycles per second or hertz..
