V f w Where V is the velocity ms f is the frequency hz. We get wave period by dividing the wavelength by the wave speed. C Speed of Light 299792458 ms f Frequency.
In order to find the denominator of the equation you need to double the value of pi 314.
Divide the angular frequency by. F 1T f 14 f 025 cycles. Wave length in meter v. Wave speed in metersecond f.
