Question

Bats are sensitive to very small changes in frequency of the reflected waves. What information does this allow them to determine about their prey?

A. Size
B. Speed 
C. Distance 
D. Species

Answer 1

Option-(B): Speed.

Step-by-step explanation:

• Echolocation:

The bats are more advance specie like many other, as they posses the adaptability to emit the ultra sonic way in a specific direction. As, the rays when reflected back in a given medium gives the measurement of the prey's speed or we can say the bat's gets the idea about the velocity of its prey. As echolocation makes it easy for the bats to know about the velocity of its prey.

• Note:

The frequency,f of the ultra sonic wave is around 20-100 kilohertz(K Hz).

Answer 2

A

Step-by-step explanation:

The size of the insect can enable them to sense the information through echolocation of the sound it produce.
