Vedclass · Answer

(A) When a beetle moves along the sand,it creates disturbances that travel as waves on the sand's surface. These disturbances consist of two types of pulses: longitudinal waves (which travel faster) and transverse waves (which travel slower). The sand scorpion is highly sensitive to these vibrations. By sensing the time interval between the arrival of the longitudinal waves and the transverse waves,the scorpion can calculate the distance to the beetle. Furthermore,by comparing the signals received by its different legs,the scorpion can determine the direction of the beetle. Thus,the Reason correctly explains how the scorpion detects and locates the beetle.
