sagedusvõnked
Sagedusvõnked, often translated as frequency oscillations or fluctuations, refers to variations in the rate at which a recurring phenomenon occurs. In physics, this concept is fundamental to understanding waves, whether they are sound waves, light waves, or electromagnetic waves. The frequency of a wave determines its pitch for sound and its color for light. When these frequencies change or fluctuate, it can lead to observable effects. For example, the Doppler effect describes the change in frequency of a wave in relation to an observer who is moving relative to the wave source. This is why a siren sounds higher as it approaches and lower as it moves away.
In a broader sense, sagedusvõnked can also be applied to non-wave phenomena. In economics, for instance, business
