Abstract: Ultrasonic waves at 44.7 KHz were used to investigate the effect of reflector's shape and area on the reflected fundamental and second harmonic pulse amplitudes. The work was carried out in the normal air medium. The technique of varying the time of flight of ultrasonic pulses along with the improved measuring system revealed reproducible patterns of the reflected fundamental and second harmonic pulse amplitudes of a particular reflector shape. Results of various reflector shapes were compared.
