Here is a long tube installed with one end closed. At the open end make a short, low noise.<\/span><\/p>\n

What did you observe?\u00a0
<\/em><\/strong>You can hear a clear echo of your voice.<\/span>

The science behind it :
<\/em><\/strong>For getting a clear echo, there must be a minimum time lag of 1\/10th of a second between the original sound and its echo.The velocity of sound is 340m\/s. The length of the tube is 18 meters. The sound wave travels 36 meters totally. The sound wave takes more than 1\/10th of a second to cross the total length of the tube and return to our ears.<\/span><\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
