Homework Statement
An ultrasound unit sends a 2.40 MHz sound wave into a 25.0-cm-long tube filled with an unknown liquid. A small microphone right next to the ultrasonic generator detects both the transmitted wave and the sound wave that has reflected off the far end of the tube. The two sound pulses are 4.40 divisions apart on an oscilloscope for which the horizontal time sweep is set to 100μs/division
What is the speed of sound in this liquid?
