∙ 9y agomi= summation (mj) is the equation and it means that it counts all the observations together.

Clear as mud!
Suppose you have a variable X that can take the values xi and that x1<x2< ... < xn.
And you have a frequency distribution function
f(xi) = mi for each value of i
Then
the cumulative frequency distribution is
F(xk) = f(x1)+f(x2) + ... +f(xk) = m1+m2+...mk
that is, F(xk) is the sum of all the frequencies up to and including k.
In other words, it is the number of times (frequency) that the result was less than or equal to xk.

∙ 9y agovelocity = frequency multiply wavelength Rearrange the equation to find the frequency
Frequency = Wave speed / Wavelength.
Planck's Equation Energy=hf where h is Planck's Constant and f is the frequency.
Wavespeed = frequency x wavelength
An equation just has an equal sign. A function is basically just an equation without one!
The threshold frequency is the minimum frequency of light required to eject electrons from a metal surface (photoelectric effect). The work function is the minimum energy needed to remove an electron from the metal surface. The threshold frequency is directly related to the work function through the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency.
velocity = frequency multiply wavelength Rearrange the equation to find the frequency
The equation that shows how wavelength is related to velocity and frequency is: wavelength = velocity / frequency. This equation is derived from the wave equation, which states that the speed of a wave is equal to its frequency multiplied by its wavelength.
The frequency in Planck's equation refers to the frequency of electromagnetic radiation, such as light. The equation relates the energy of a photon to its frequency through the constant known as Planck's constant.
The equation that relates wavelength and frequency is: speed of light = wavelength x frequency. This equation shows that as the frequency of a wave increases, its wavelength decreases, and vice versa.
frequency density = frequency/group width
Frequency = Wave speed / Wavelength.
There is no such equation. The main reason is that there is no relationship between current and frequency.
Planck's Equation Energy=hf where h is Planck's Constant and f is the frequency.
Wavelength and frequency are inversely proportional in the wavelength-frequency equation. This means that as the wavelength of a wave increases, the frequency decreases, and vice versa.
The equation velocity equals wavelength multiplied by frequency is called the wave equation. It describes the relationship between the speed of a wave, its wavelength, and its frequency.
Threshold frequency is the minimum frequency of light required to eject an electron from a metal surface, while work function is the minimum energy required to remove an electron from the metal. The threshold frequency is directly related to the work function by the equation E = hf, where E is the energy required, h is Planck's constant, and f is the frequency of the incident light.
