To calculate wave frequency in physics, one must know about the variables used in different formulas. One formula states that frequency (f) is equal to the wave velocity (v) divided by the wavelength (λ), or f = v/ (λ). If you know the period (T), another formula you can use is that frequency is the reciprocal of the period, or f= 1/T.
Know MoreThere is another formula that states that the angular frequency (ω) is equal to 2 multiplied by pi and the frequency, or ω = 2πf. From this formula, one can calculate frequency (f) by dividing both sides of the equation by 2π to find that f= ω/2π.
The frequency (f) is the number of waves per unit time, and its measurement unit is in Hertz (Hz).
The wavelength (λ) is the distance between one point on a wave to the exact same point on the adjacent wave, and its measurement is in meters. The wave velocity (v) measurement is meters per second. Likewise, the period (T) of a wave is the time it takes for one complete oscillation, and it is measured in seconds.
In order to calculate frequency, one must know at least some of the variables in these formulas.

For example, there are two possible outcomes when a coin is tossed in the air, and the probability of the coin landing on a head or a tail is equal to 0.5.
Full Answer >To calculate moles, begin by identifying the number of grams of the substance, and calculate its molar mass. Divide the number of grams by the molar mass of the compound to make the conversion to moles.
Full Answer >Calculate an average by using this formula: sum of elements / number of elements. Find the sum of the elements by adding up the values of all the numbers in the set. Find the number of elements by counting how many different values are in the set.
Full Answer >Calculate the median of a set by putting the numbers in order from least to greatest and finding the middle number, when there is an odd number of values in the set. When there is an even number of values, find the median by averaging the two middle values.
