Bats use a process called echolocation to find their food. This involves giving out sound waves that hit possible prey or food. When the waves hit an object, they bounce back to the bat, allowing the bat to locate its prey.
What type of wave interaction is echolocation?
a. absortion
b. diffraction
c. reflection
d. refraction
Answers
Answer: c) Reflection
Explanation: Thanks for the A2A. As the given description clearly says, the sound waves hit a surface and 'bounce back'. This is the phenomenon of Reflection and thus option (C) is the right answer.
Hope it helps :)
Option c.
Reflection
Bats use sound waves of about 20 to 200 kilohertz to found out the food or prey.
In this technique, Sound waves are passed from body. These waves then strike another body and reflect back by striking. This is known as reflection of sound waves.
This technique is also used in submarines and other mammals too (like dolphins)
The time taken by waves to come to the body back can be used to determine the distance between the food/prey (or other substance) and the sender (who passed the waves)
This whole process is known as echolocation.
