Ultrasonic Diffraction using Goniometer

Holmarc’s Ultrasonic Diffraction with Goniometer (Model No. HO-ED-A-03) is a standard classical diffraction experiment used in physics laboratories to study the diffraction of light by ultrasonic waves. When an ultrasonic wave propagates through a medium, the molecules of the medium vibrate over very small distances in a direction parallel to the direction of propagation of the longitudinal wave.

The ultrasonic diffraction experimental setup uses a sodium lamp as the light source. When sodium light passes through the liquid contained in the glass tank, a clear higher-order diffraction pattern can be observed through the eyepiece of the spectrometer. The high-resolution spectroscopic goniometer stage enables accurate observation and measurement of the diffraction fringes at different ultrasonic frequencies.

The ultrasonic waves generated by the piezoelectric transducer propagate through the liquid medium and are reflected from the flat glass plate at the opposite side of the cell. The incident and reflected ultrasonic waves interfere with each other, forming a stationary or standing wave pattern in the liquid.

The piezoelectric crystals are mounted at the centre of the goniometer using a kinematic holder. This arrangement allows the sodium light beam to pass conveniently through the liquid medium and reach the eyepiece through the spectroscopic arm.

The diffraction pattern varies with the frequency of the ultrasonic waves. By using piezoelectric crystals of different frequencies, such as 3 MHz to 5 MHz, the corresponding changes in the diffraction pattern can be observed and studied.

The velocity of ultrasonic waves in the liquid medium can be calculated from the observed diffraction pattern and the known wavelength of the light.
