The probe used in a medical ultrasound examination emits sound waves in air that have a wavelength of 0.12 mm. what is the wavelength of the sound waves in the patient? a) 0.54 mm b) 0.12 mm c) 0.26 mm d) 0.027 mm

As we know that wavelength of ultrasound in air is given as

now as the wave travel from air to any other denser medium the magnitude of wavelength will decrease by some factor

so here as the ultrasound wave will travel inside the person it will decrease by some factor

so the answer must be less than 0.12 mm

so the correct answer must be

d) 0.027 mm
