Ultrasonic wave entering liquid solvent from air.
Ultrasonic wave entering liquid solvent from air.
An ultrasonic transducer operating at a frequency of \(40 \text{ kHz}\) generates longitudinal sound waves in air that travel into a bath of liquid chemical solvent. The speed of sound in air is \(340 \text{ m/s}\), and the speed of sound in the liquid solvent is \(1360 \text{ m/s}\). Which of the following correctly identifies the frequency \(f_{\text{solvent}}\text{ control}\) and wavelength \(\lambda_{\text{solvent}}\text{ control}\) of the ultrasonic wave inside the solvent?
