For rotating devices, it is symbolized by omega and expressed in revolutions per second.
The energy of electromagnetic waves is obtained by multiplying Planck's constant "h" by this quantity. When an object such as a bridge vibrates at the natural state of this quantity, resonance occurs. For rotating devices, it is symbolized by omega and expressed in revolutions per second. For 10 points, name this property referring to the number of occurrences of a repeating event per unit time, which is measured in Hertz.
