A student watches a ball game on the school field. The student sees the ball being hit with a bat but he hears the sound a short time after. This is because the speed of light is much greater than the speed of sound. Describe an experiment which measures the speed of sound in air. In your answer describe the measurements, calculations and procedures needed to gather accurate and reliable results. – 7521

1. To measure the speed of sound, you can start with an action that produces sound, like clapping two wooden blocks together, which can be seen and heard.
   Then, measure the distance between the person making the sound and the observer (or between a speaker and a microphone).
   Next, measure the time it takes for the sound to travel that distance — for example, by using a stopwatch, microphones, or a CRO (cathode ray oscilloscope).
   Use the formula:
   speed = distance ÷ time
   To improve the experiment, you could repeat it several times and take an average, use a longer distance, or try a different method or equipment to make the results more accurate.
