Description
Sound waves rely on a medium to propagate through space. Although in most cases, sound travels through mediums such as air or water, light can serve as a medium and can be analyzed to find the wave patterns for sound at varying frequencies. This is accomplished by sending a laser through an optical cable that can be sent into rapid propagation similar to a guitar string. Using appropriate Fourier analysis methods, variances in the light frequencies within the cable can be attributed to added sound vibrations caused by the vibrations of the cable; these sound vibrations can be isolated and translated into sinusoidal wave functions. This setup can be expanded to represent a full guitar by adding cables and simultaneously translating these wave functions into specific pitches to form melodic notes and chords.
