There are many physical phenomena that can be modelled by sine waves:

Waves in water are an obvious example,

Also, สุขภาพดีกับน้ำผลไม้ผง more complicated motion can be modelled by a superposition of many sine waves (using Fourier transforms). This enables complex motions to be studied more easily.
