Final answer:
The process for determining the time it takes for sound waves to travel using a stopwatch.
Step-by-step explanation:
The process for used stop sticks that have been struck can be explained using the physics concept of sound waves. When the stop stick is struck, it vibrates and creates sound waves that travel through the air. These sound waves can be detected by someone standing at a different point using a stopwatch.
To determine the time it takes for the sound waves to travel from the point of strike to the point of detection, the person with the stopwatch should start the stopwatch when they see the other person make the sound and stop the stopwatch when they hear the sound. By repeating this process multiple times and recording the times, the average time can be calculated.
