Longitudinal and transverse waves Sound is transmitted through gases‚ plasma‚ and liquids as longitudinal waves‚ also called compression waves. Through solids‚ however‚ it can be transmitted as both longitudinal waves and transverse waves. Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure‚ causing local regions of compression and rarefaction‚ while transverse waves are waves of alternating shear stress at right angle to the direction of propagation

What are UltraSonic Waves? Ultrasonic waves are sound waves with frequencies high about human hearing and short wave lengths. Sound waves have frequencies about 20‚000 to 100‚000. Also Ultrasound frequencies range from 20 kHz (the upper range of hearing for a young adult human) through 150 kHz (audible to some bats and other creatures)‚ right up to 10 MHz (used in some medical treatments and industrial cleaning applications). While these frequencies overlap with those of radio waves‚ they are different

The waves are further classified by the kinds of motions they incur to rock particles. Primary or compressional waves‚ known as P waves‚ send particles moving back and forth in the same direction as the waves are traveling‚ as secondary or transverse shear waves‚ known as S waves‚ create vibrations perpendicular
