What is echolocation & how do bats use it? | Wildlife Online

Most bats 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-lag between the emitted and 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. Approximate the speed of the sound waves as 345 m/s.36.2 ×10^-2 s or, 36.2 millisecond72.5 ×10^-3
