14.6 A bat emits ultrasonic sound of frequency 1000 kHz in air. If the sound meets a water surface, what is the wavelength of (a) the reflected sound, (b) the transmitted sound? Speed of sound in air is 340ms−1 and in water 1486ms−1.
(a) What is the wavelength of the reflected sound?
(b) What is the wavelength of the transmitted sound?
