| Περίληψη: | This paper presents a thorough method for studying the interference of water waves. The study aimed: (a) to demonstrate the interaction of two coherent waves, which creates interference patterns, and (b) to analyse the interference patterns. Three main tools were employed: a simplified ripple tank to experiment, a smartphone camera to record the experiment, and Tracker to quantify the experiment video. The quantification was designed to investigate experimental measurement, asymptotic approximation and linear approximation of the interference patterns. The results showed that the demonstration was impressive in that the interference patterns were appealingly depicted in the video recording. The quantification was highly accurate, with an error of about 3%. The investigation indicated that the measured values agreed with the asymptotic prediction throughout the entire range, with errors of about 3%. Errors between the measured values and linear approximation dramatically increased from the fourth pattern. The findings caution teaching and learning against using the linear approximation for predicting interference patterns of water waves. In conclusion, this study exposes implications for teaching and learning interference phenomena comprehensively. |
