Report #1: Sounds

Introduction

This lab focuses on exploring sound waves and their properties, specifically how they travel
through air. Sound waves are mechanical vibrations that move through mediums like air,
produced by vibrating objects such as a tuning fork or speaker. These vibrations cause
fluctuations in air pressure, allowing sound to propagate. In this experiment, we will
examine three sound sources to measure their frequencies and calculate the speed of
sound in our environment. LoggerPro software will be used to accurately capture and
analyze the sound waves. The first experiment uses a tuning fork to create sound waves,
which will be recorded and studied. In the second, we will generate sound waves using our
voices to find the frequency of the note produced. The final experiment will involve
measuring the speed of sound using a cardboard tube to create an echo chamber. By
timing the echo, we can determine how fast sound travels. In all experiments, the expected
result is that the speed of sound should be close to 343 meters per second (m/s) at room
temperature (20°C), helping us better understand sound wave behavior and measurement
techniques.

Data and Calculations

Experiment 1: Tuning Fork

Table 1: Experiment 1

, Experiment 1: Measurements

Period of Tuning Fork [s] = 0.003

Calculations: 2.733- 2.730 = 0.003 s

Frequency of Tuning Fork [Hz] = 333.3

Calculations: 𝑓 = 1/T

= 1/( 0.003) = 333.3 Hz
