Velocity of ultrasound in solid state material
Item no.: P5160100
The velocity of sound in acrylics shall be determined by time of flight reflection technique with an ultrasonic echoscope. The measurements are done by reflection method, on three cylinders of different length. Two measurement series are carried out with ultrasonic probes of different frequencies.
영문 설명서
Tasks

1. Measure the length of the three cylinders with the caliper.
2. Determine the time of flight of the ultrasonic reflection pulses for the three cylinders and the two ultrasonic probes.
3. Calculate the sound velocities, probe delays and use the two mean values obtained to calculate the cylinder length.
