...it will travel to the mouth of this tube with the velocity of sound. Here an echo of the pulsation will be formed which will run back again, be reflected...the motion is destroyed by friction and imperfect reflection. . . . The effect therefore will be a propagation from the mouth of the tube of a succession... | |

Euler, if a single pulsation be excited at the bottom of a tube closed at one end, it will travel to the mouth of this tube with the velocity of sound. Here an echo of the pulsation will be formed which will run back again, be reflected from the bottom...
