What is Speed of Sound in Steel Rails about?

The document describes an experiment to measure the thickness of a steel rail using ultrasound. A sound pulse was emitted into the rail and the echo detected on an oscilloscope. The pulse and echo are shown on the trace. The thickness was calculated using the known frequency of the ultrasound (3.8 MHz) and speed of sound in steel (5900 m/s). From this, the thickness of the steel rail was determined to be approximately 0.87 mm.
