Concept explainers
To Explain: The effect on the times for runners if the timing started when sound was heard.
Answer to Problem 26A
Runners will get less time for race when the sound of piston is used.
Explanation of Solution
Introduction:
Sound is a mechanical wave which requires medium for its propagation. It is a longitudinal wave in which the direction of the displacement of particle is in the same or opposite to the direction in which wave propagates.
Light is
The
The approximate speed of sound in air is
If the running time start when the sound was heard instead of sight from starter’s pistol then runners will get less time for
The time taken by light to reach at the officials at the finish line will be negligible as compared as compared to time take by sound from piston.
Therefore, runners will get less time for race when the sound of piston is used.
