in a experiment to measure the speed of sound in glass, a pulse of sound is sent into a glass rod, 14 m in length. the reflected sound is detected after 5.6 ms (0.0056 s). calculate the speed of sound in glass.
d = r*t = 14
r = 14/t = 14/(0.0056/2) = 5000 m/s.
In an experiment to measure the speed of sound in glass, a pulse of sound is sent into a glass rod, 14.0 m in length. The reflected sound is detected after 5.6ms (0.0056s). Calculate the speed of sound in glass.
To calculate the speed of sound in glass, we can use the formula:
Speed of sound = Distance / Time
Given:
Distance = 14 m
Time = 0.0056 s
Using the formula, we can calculate the speed of sound in glass:
Speed of sound = 14 m / 0.0056 s = 2500 m/s
Therefore, the speed of sound in glass is 2500 m/s.
To calculate the speed of sound in glass, we can use the formula:
Speed of sound = Distance / Time
In this case, the distance traveled by the sound is twice the length of the glass rod because the sound wave has to travel to the end of the rod and then back to the source.
Distance = 2 * Length of the glass rod = 2 * 14 m = 28 m
The time it takes for the sound to travel this distance is given as 0.0056 s.
Now we can plug in these values into the formula to calculate the speed of sound in glass:
Speed of sound = 28 m / 0.0056 s = 5000 m/s
Therefore, the speed of sound in the glass is 5000 m/s.
