Dec 28, 2020 · The frequency and period of a wave are two of the most important characteristics of any wave, whether it's a light wave or the sea waves lapping up on the shore. Frequency tells you the number of oscillations of something per unit of time, and period tells you the length of the oscillation.

The allele frequency is the number of individual alleles of a certain type, divided by the total number of alleles of all types in a population. In simple terms, the allele frequency describes how common an allele is within a population.
The allele frequency is different from the phenotypic ratioin that it accounts for all alleles, even if they are recessive and are “hidden” within carrier organisms. The phenotypic ratio only describes the phenotypes, or actual physical features that are present within a population. To find the allele frequency, scientists must consider heterozygou...
To find the number of alleles in a given population, you must look at all the phenotypes present. The phenotypes that represent the allele are often masked by dominant and recessive alleles working in conjunction. To analyze the allele frequency in a population, scientists use the Hardy-Weinberg (HW) equation.The Hardy-Weinberg equation is written ...
In a simplified scenario, p and q are the only alleles in the population, and the population is not developing any mutations.If this is the case, the sum of the allele frequencies of p and q must equal 1 because with only two alleles the combined frequency must equal 100%.
Trying to Find p First
One mistake that students commonly make is trying to calculate p by observing the population, then taking the square root. This does not work in typical recessive/dominant allele relationships, simply because a dominant allele can hide a recessive allele. For instance, if we were to calculate the square root of .84 (proportion of black rabbits), we would get nearly 92%. This overestimates the p allele frequency because of the fact that heterozygous phenotypes are actually hiding a recessive a...
Relating Allele Frequency to Fitness
A common misconception of allele frequency is that it is directly related to the evolutionary fitness of a particular allele. Just because an allele is frequent or infrequent has no bearing on the fitness of that allele.For example, many recessive traits that are deleterious “hide” in a population. This can mean that while it appears to exist at really low levels, it is in fact just hiding in the hybrids of the population. Other times, a new beneficial mutation will have a very low allele fre...

May 16, 2021 · The wavelength to frequency and frequency to wavelength calculations are important in physics and engineering. Here is the equation relating wavelength and frequency, example calculations, and a table of common values.
Music has many mathematical elements in it: rhythm, pitch, scale, frequency, interval, and ratio. There are many ways to turn these elements into a science fair project. You can investigate how the scale is based upon a special type of number sequence called a Harmonic Series.
You'll use historical climate data to look at moisture conditions in regions across the continental U.S. You'll use a spreadsheet program to calculate the frequency of different moisture conditions for each region and make graphs for comparison.
We can calculate frequency using specific formulas that take into account other related quantities like time period, wave speed, and wavelength. These formulas help us understand the behavior of waves and how they propagate through space. Formula 1: Frequency formula based on time period (T): f = 1 T.
