The distance from A to B is 42.8 cm and the distance from C to D is 12.4 cm. Determine the wavelength, wave speed and amplitude of this wave 3. Microbats use echolocation to navigate and hunt. They emit pulses of high frequency sound waves which reflect off obstacles and objects in their surroundings. By detecting the time delay between the emitted pulse and the return of the reflected pulse, a bat can determine the location of the object. Determine the time delay between the sending of a pulse and the return of its reflection from an object located 12.5 m away.
