Ultrasonic diffraction Experimental setup Make – HOLMARC (Model – HO-ED-A-01A) The Ultrasonic diffraction apparatus will be used to study diffraction of light by ultrasonic waves. Ultrasonic sound refers to sound with a frequency greater than the human audible range (20Hz to 20 KHz). The apparatus should consist of a graduated rail and rail carriages appropriately fitted with a laser head, an RF oscillator, a glass tank mount with crystal holder and a screen. The ultrasonic waves generated by the transducer travels down the medium (liquid)and gets reflected at the bottom (flat glass plate) of the cell. The incident and reflected waves interfere and a stationary / standing wave pattern is formed. The pattern can be observed on a screen or a wall and we can plot diffraction pattern on a graph paper for further calculations.
