Frequency (f) = 1/Period (T) 2.Characterizing Sound Waves: The frequency of sound waves determines its pitch. As an example, consider a string on a musical instrument vibrating 440 times per second.

Natural Frequency (f) = (1 / 2π) * √(k / m) Where: – k is the spring constant or stiffness – m is the mass attached to the spring. To calculate natural frequency: a) Determine both ‘k’ (stiffness of ...
