Motion I 2.1 What is the speed of sound? 334.90 m/s Can you think of why speed of sound may vary day to day? Atmospheric pressure, weather, and moisture in the air certainly have an effect on sound waves. Although the speed of sound is constant, the ability to detect the waves may be altered due to the abovementioned qualities. At 120 Hz, what was the maximum measurable distance? 0.0660m Can you think of why the maximum distance depends on the trigger rate? As the frequency of the trigger rate increases, the maximum distance decreases. For example, a distance of greater than 0.0660m is immeasurable at 120 Hz. At a greater distance, the sensor would be unable to accurately locate a position, record it in the sensor, and still have enough time to fire at a pace of 120 Hz. At lower frequencies, the sensor fires out at a lesser time interval, so a farther distance can be recorded. 2.2
