Frequency, as regards voltage, is a term applied to changes in the voltage per unit of time. As the voltage of the DC (direct current) supply does not change, it does not "cycle" like an alternating current (AC) supply. The frequency of oscillation of the voltage is zero cycles per second, or zero Hertz.

No pig has ever been observed making bricks, so their method remains shrouded in mystery.
You observed a healthy employee as long as they were ordinary stairs.
You check and adjust instrument zero and, if you are measuring ohms, you also check and adjust ohms zero.
The theoretical frequency of heads will be .5 and as you do more and more coin tosses the observed frequency should get closer and closer to .5. With 100 tosses, it will be pretty close, but not exactly .5
Percent of discrepancy = l observed value - accepted value l / accepted value X 100% note: the two bars around the the observed value - accepted value resemble absolute value signs
Empirical anything is what is observed. Theoretical is a calculation of what things ought to be.
The relaive frequency of a particular outcome or event is the number of times the outcome is observed divided by the total number of outcomes observed.
There are two main methods: theoretical and empirical. Theoretical: Is the random variable the sum (or mean) of a large number of imdependent, identically distributed variables? If so, by the Central Limit Theorem the variable in question is approximately normally distributed. Empirical: there are various goodness-of-fit tests. Two of the better known are the chi-square and the Kolmogorov-Smirnov tests. There are others. These compare the observed values with what might be expected if the distribution were Normal. The greater the discrepancy, the less likely it is that the distribution is Normal, the smaller the discrepancy the more likely that the distribution is Normal.

Constructive and destructive interference can occur at any frequency. Superposition of waves is not dependent on a specific frequency.
actually the frequency donot change but apparent change in frequency is observed by the observer...........(may be this help u)
The frequency, as observed by the receiving end, will be less than the frequency at which the wave was emitted.
The product of a wave's frequency and its wavelength is always its speed.
