In general, ω is the angular speed - the rate change of angle (as in a circular motion). Frequency (f) is 1/T or the number of periodic oscillations or revolutions during a given time period. Angular speed or angular frequency, relates the same idea to angles - how much angle is covered over a time period.
What is the difference between the frequency F and the frequency ω?
So, the formula for angular frequency will be, ω =2π/T, where ω is the angular frequency, 2π is the angular displacement, and T is the time period. In the case of frequency, it is the number of repeated events per unit time. So, the formula for frequency will be, f= 1 / T, where T is time.
What is the difference between omega and F for frequency?
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
What is the relationship between frequency F and wavelength?
A function is most often denoted by letters such as f, g and h, and the value of a function f at an element x of its domain is denoted by f(x); the numerical value resulting from the function evaluation at a particular input value is denoted by replacing x with this value; for example, the value of f at x = 4 is ...

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Example.
