relative frequency approximation

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..

The difference between these two values is called the absolute error. Absolute Error = Original number - Approximated number The ratio of the absolute error and the original number expressed in percentage form is called percentage relative erro..

From the above examples on approximation, we observe that the approximated value may be more or less than the original number. The difference between these two values is called the absolute error. Absolute Error = Original number - Approximated number The ratio of the ..

Relation Between Atomic Number and Atomic Mass - While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well. ..

While studying the periodic table, it will be noticed that with the increase in the atomic number, there is an increase in atomic mass as well (with some exceptions). Usually an element with high atomic number has high atomic mass as well. If you recall from earlier lessons, Atomic number (Z) is t..

Whenever there is a relative motion between a source of light and the observer, the apparent frequency of light received by the observer is different from the true frequency of light emitted actually from the source of ligh..

As the threshold of audibility varies with frequency, sounds of the same intensity but different frequencies are found to differ in loudness. Therefore, another unit of loudness is defined. This unit measures the intensity of a sound relative to a reference tone of def..

A chromosome map is a graphic representation of a linkage group in the form of a line which shows by points the sequence of the genes and the relative distance between the genes it contains. A chromosomes map is also called a linkage map or genetic map. Since the frequency of cr..

Let a stationary observer on a platform listen to the sound emitted by the whistle of an incoming train. As the train approaches the platform, an increase in the pitch of the sound will be observed. As the engine moves away from him, there will be a decrease in the pitch of the sound. The same effe..

Doppler Effect - Let a stationary observer on a platform listen to the sound emitted by the whistle of an incoming train. As the train approaches the platform, an increase in the pitch of the sound will be observed. As the engine moves away from him, there will be a decrease in the pitch of the sou..
