2024/2025
Ultrasonic Waves that travel along the surface of a material and whose particle motion is

elliptical.


 Rayleigh Waves (Surface/Love Waves)


In a material with a given velocity, when frequency is increased, the wavelength will __?

 Decrease


Ultrasonic vibrations can be propagated only in the longitudinal mode in which media?

 Machine Oil (Liquid)


If a 5.0 Mhz transducer is substituted for a 2.25 Mhz transducer ( 2.25 old/5.0 new), what

would be the effect on the wavelength of the longitudinal wave mode produced in the test

specimen. (i.e. shorter, longer or same)?

 Wavelength would decrease (Mhz increase = wavelength decrease)


The velocity of a sound in a material is dependent upon the: Frequency of the wave,

Wavelength, Material Properties, Vibration Cycle.


 Material Properties


To vary or change the wavelength of sound being used to test a part, you would change the:

Sound Wave Frequency, Diameter of the Transducer, Electrical Pulse Voltage , Pulse

Repetition Rate.
