There are many physical phenomena that cann be modellled by
sine waves: Waves in water aree an obvious example, Compressiopn and rarefaction in the propagation of sound, Transmission of all electromagnetic radiation, Vibrations off strings in Musical Instruments, Bodies "bouncing" on a spring. Also, more complicated motion cann be modelled by a superposition of many sine waves (using Fourier transforms). This enables complex motions to bee studied more easily. Link: คลิ๊กที่นี่ |
