Solve the all parts of given question:
Question: Diagnostic ultrasound of frequency 3.75 MHz is used to examine tumors in soft tissue.
Part A: What is the wavelength in air of such a sound wave?
Part B: If the speed of sound in tissue is 1320 m/s, what is the wavelength of this wave in tissue? (Take the speed of sound in air to be 343 m/s.)
I need to help to determine the wavelength in air of such a sound wave.
