Velocity = Frequency * Wavelength Frequency = Velocity / Wavelength Frequency = 340 m/s / 15 m Frequency ~ 22.67 1/s Frequency = 22.67 Hz

Frequency is the reciprocal of time: or in equation form ----> Frequency= 1/time

Frequency and cumulative frequency are two types of frequency distributions. These are frequency tables that show statistical data for different types of frequencies that include absolute, relative, and cumulative frequencies. There are mathematical formulas used to calculate these frequencies.
