Webb19 jan. 2024 · The formula for calculating undamped natural frequency: ω o = √ ( ao / a2) Where: ω o = Undamped Natural Frequency a o = Co-efficient a 2 = Co-efficient Let’s solve an example; Find the undamped natural frequency when the co-efficient is 32 and the co-efficient is 3. This implies that; a o = Co-efficient = 32 a 2 = Co-efficient = 3 WebbThe time period is the time taken by a complete cycle of the wave to pass a point. Angular frequency is angular displacement of any element of the wave per unit of time. Consider the graph shown below. It represents the displacement y of any element for a harmonic wave along a string moving in the positive x-direction with respect to time.
