The wavelength of an ultrasonic wave is :

A hospital uses an ultrasonic scanner of frequency 3.2 MHz to locate the tumours in a tissue. The wavelength of ultrasonic waves in tissue in which the speed of the wave is 1.6 km/s is

Ultrasonic waves of frequency 4.5 MHz are used to detect tumour in soft tissues. The speed of sound in tissue is 1.5 km s^-1 and that in air is 340 m s^-1 . Find the wavelength of this ultrasonic wave in air and in tissue.
