An Introduction to Sound - Results Tables

Exploring the science of sound through practical experiments, one investigation centres on whether the length of a ruler influences the sound it produces. The study compares the sounds made by both plastic and wooden rulers of varying lengths, from 4 cm to 20 cm. This comparison aims to determine if there's a correlation between the length of the ruler and the pitch or quality of the sound when the ruler is flicked or snapped against a surface.

Another aspect of the study includes a 'Tuning Fork Investigation' where the length of the tuning fork, measured in millimetres, is recorded alongside the frequency of the sound it emits, measured in Hertz (Hz). This data is used to identify the musical note produced and to describe the sound made. Additionally, the research delves into the musical potential of a home-made guitar, questioning how many notes can be produced. This is examined by varying the width of the elastic band used as a string and the number of frets on the instrument, which range from narrow to wide. These experiments are designed to offer insights into the physics of sound and how different variables can affect musical pitch and tone.
