a boy stands at a distance of 175 m from a high wall. He claps his hands and hears an echo after one second. Calculate the speed of sound in air.
the round trip is 350 m.
So, the speed of sound is 350m/s
A boy stand at a distance of 175 meters from high wall he claps the hands and hear the echo after 1 second calculate it's speed of sound in air
350 m/sec
Easy
To calculate the speed of sound in air, we can use the formula:
Speed of sound = Distance ÷ Time
In this case, the boy claps his hands and hears the echo after one second. This time includes both the time taken for the sound to travel to the wall and back to the boy.
However, we need to consider that the sound travels to the wall (175 m) and back to the boy, so the total distance covered by the sound is twice the distance to the wall:
Total Distance = 2 × Distance to the wall
Plugging in the values, we have:
Total Distance = 2 × 175 m = 350 m
Time = 1 second
Now, we can calculate the speed of sound:
Speed of sound = Total Distance ÷ Time
Speed of sound = 350 m ÷ 1 second
Speed of sound = 350 m/s
Therefore, the speed of sound in air is 350 m/s.
