Abstract

Acoustic resonance in closed cavities is a fundamental phenomenon in wave physics influenced by system geometry, medium properties, and acoustic boundary conditions. This study aims to analyze the variation of acoustic resonance frequencies in fluid-filled cavities while exploring the role of computational modeling in supporting physics learning. The method employs a mathematical modeling approach based on the one-dimensional acoustic wave equation with impedance boundary conditions at the fluid–air interface. Numerical simulations are conducted to evaluate resonance frequency variation as a function of fluid height, and Fast Fourier Transform (FFT) analysis is used to identify dominant frequencies. The results show that increasing fluid height reduces the effective air-column length, leading to systematic shifts in resonance frequency. Furthermore, computational representations enable dynamic visualization of the relationship between physical variables and frequency changes, thereby supporting conceptual understanding in physics learning. These findings suggest that computational modeling can serve as an effective approach to bridge theoretical concepts and observable acoustic phenomena in educational contexts.
