Question

The phase difference between the particle at one compression and another particle in third compression is

• A. $\pi$ radians
• B. $2\pi$ radians
• C. $3\pi$ radians
• D. $4\pi$ radians

Answer 1

Answer: (D)

$4\pi$ radians

phase difference between two successive compression is $2\pi$
$\therefore$ phase difference between a particle at one compression and in third compression is $2\left(2\pi \right)=4\pi$
