11. Is the angular frequency of the wave, and c is the speed of light. 12. The energy of each packet is related to the angular frequency of the wave by the relation 13. \omega is the angular frequency of the wave, and c is the speed of light. 14. Another basic force is Euler force, which is often defined as the acceleration of angular frequency . 15. Where the is the amplitude, the wavevector, and the angular frequency , of the plane wave. 16. Determination of the angular frequencies and of the magnetic field provided the charge-to-mass ratio. 17. The nominal angular frequency \ omega _ \ mathrm { n } ( in radians per second ) is given by 18. In digital signal processing, the angular frequency may be normalized by the sampling rate, yielding the normalized frequency. 19. Where " ? " is the angular frequency at which the stored energy and power loss are measured. 20. Where " j " is the imaginary unit and ? is the angular frequency of the sinusoidal signal.
