# What is the formula for expected frequency?

You need to know the probability of the event in question. Then the expected frequency for that event occurring is that probability times the number of times the experiment was repeated.

f_b = |f_2 - f_1| is the formula for beat frequency

The formula of frequency is: f=1/T where: - T is period, in seconds - f is frequency, in hertz

The formula for frequency is: frequency = 1 / T, where T = Period. That is e.g. "cycles per second".The formula for time is: T (Period) = 1 / frequency.Note: T = Period and t = Time

For goodness of fit test using Chisquare test, Expected frequency = Total number of observations * theoretical probability specified or Expected frequency = Total number of observations / Number of categories if theoretical frequencies are not given. For contingency tables (test for independence) Expected frequency = (Row total * Column total) / Grand total for each cell

frequency = (wave speed)/(wavelength) frequency = 1/(period)

One formula is:speed (of the wave) = frequency x wavelength

velocity=frequency&times;wavelength therefore wavelength= velocity &divide; frequency

The speed is the product of wavelength and frequency.

The formula to determine speed is Speed= wavelength*frequency

Frequency = (speed) divided by (wavelength) or Frequency = (1) divided by (period of the wave)

The formula that relates speed, wavelength and frequency is speed equals wavelength times frequency. A wavelength is defined as the distance between successive crests of a wave.

The formula is frequency = Energy/h where h is Planck's Constant, 2/3 E-33.

formula: p2 + 2pq + q2 = 1 p+q=1 p = dominant (A) allele frequency q = recessive (a) allele frequency q2 = homozygous recessive frequency p2 = homozygous dominant frequency 2pq = heterozygous frequency

Probability of event = relative frequency = f/nf is the frequency of the event occurence in a sample of n observances.

the speed of light equals the frequency multiplied by the wavelength.

wavelength = c/frequency of light where c is the speed of light.

UV has a wavelenght of 400nm and less you can calculate the frequency with this formula V (frequency) = c (speed of light) / &lambda; (wavelenght)

The FIT Formula stands for : F = Frequency I = Intensity T = Time The FIT Formula helps you get better fitness.

The question is incomplete. Frequency of what? If it refers to electromagnetic waves, you won't need even frequency to determine velocity (in a vacuum), because it will always be c (the speed of light). You can compute the speed of other kinds of waves if you know the frequency and wavelength, but not from frequency alone. The formula is frequency x wavelength = velocity If the waves are electromagnetic, and you have only frequency, you can compute the wavelength using the same formula.
