In physics, you can apply Hookeâs law, along with the concept of simple harmonic motion, to find the angular frequency of a mass on a spring. And because you can relate angular frequency and the mass on the spring, you can find the displacement, velocity, and acceleration of the mass. Hookeâs law says that F [â¦]
As the wave moves by, in a time equal to the period one oscillation of the wave occurs and so the wave has moved along a distance equal to the wavelength. The velocity of the wave is then given by. since the frequency is the inverse of the period. pendulum that takes 0.5 seconds to make one full oscillation has a frequency of 1 oscillation per 0.5 second, or 2 oscillations per second. The commonly used unit for the number of oscillations per second is the Hertz, so that this same pendulum is said to have a frequency of 2 Hertz, or 2 Hz.
