Statement – 1: Newton’s equation for speed of sound in air was found wrong because, he assumed process as isothermal
Statement – 2: Flow of sound wave in a medium is very fast. Quick process suppress heat exchange, hence this process must be adiabatic in nature.
Statement – 2: Flow of sound wave in a medium is very fast. Quick process suppress heat exchange, hence this process must be adiabatic in nature.
View answer and explanation
Correct option: A
Statement – 1 is true, Statement – 2 is true; Statement – 2 is a correct explanation for Statement – 1
Option A (Statement – 1 is true, Statement – 2 is true; Statement – 2 is a correct explanation for Statement – 1) is correct because Newton's assumption of an isothermal process for sound propagation was incorrect, and the adiabatic process is a better approximation due to the rapid nature of sound waves.
