Excels FREQUENCY function lets you count how many times values fall within specific ranges. Something that repeats once per second has a period of 1 s. Angular frequency 2 p period of oscillation.
The formula for time is.
Frequency to joules formula is defined as e 662610 -34 f where f is the frequency and 662610 -34 is the Planks Constant in Joules. Light waves move through a vacuum at the same speed the number of wave crests depends on the wavelength. Excels FREQUENCY function lets you count how many times values fall within specific ranges. In general the frequency is the reciprocal of the period or time interval.
