Question

Match the following columns :

Answer 1

(A) : Bats use ultrasonic waves to detect the obstacle in their paths.
(B) : Netwon suggested that the exchange of energy takes place between the rarefaction-compression pulses with the surrounding via isothermal process.
Newton's formula of speed of sound in gas medium $v=\sqrt{\frac{E}{d}}$
(C) : Laplace proposed that the exchange of energy takes place between the rarefaction-compression pulses with the surrounding via adiabatic process.
Laplace's formula of speed of sound in gas medium $v=\sqrt{\frac{\gamma P}{d}}$
(D) : SONAR (SOund Navigation And Ranging) is based on the reflection of sound waves from the obstacle and is used to determine the depth of sea and ocean.
(E) : Reverberation is the phenomenon of multiple reflection of sound from the walls of auditorium and the amplitude of sound gets reduced after each reflection.
