The minimum time interval that the human ear can detect between two claps of the stick is 0.1 second. When this interval between the clap and the echo is shorter than 0.1 second, no echo is heard. This is why no echo was heard when standing only 10 meters in front of the wall. The time it took the echo to come back at this distance must be 0.1 second. 6. Can you find out from the information collected how fast the sound was traveling through the air? [The echo should be heard at about 17 m in front of the wall. This would mean that the sound traveled to the wall and back (2 x 17m) in 0.1 second. This means that the speed of sound is about 34m/0.1 second or about 340 m/second.] CLASS RESPONSE / CONCEPT INVENTION
