Derivation of Beat Frequency Formula: Consider sound from two different sources whose medium is air is meeting at a point p. Let us assume that one source has a shorter time period as T S and high frequency as f 2 whereas other source time periods and frequency are T L and f 1.With the help of these frequencies, we represent beat frequency by showing the relationship between these two frequencies. Fit is defined as the degree of freedom of tightness between the mating parts in an assembly process, it is also defined as the relationship between the hole and the shaft during the Assembly is called Fit.In this article, we are going to discuss different types of Fits in a detailed way.. Other articles where Constructive interference is discussed: interference: …wave amplitudes are reinforced, producing constructive interference; but, if the two waves are out of phase by 1 2 period (i.e., one is minimum when the other is maximum), the result is destructive interference, producing complete annulment if they are of equal amplitude.
