MCQ
$y = A \sin \left(\frac{\omega x}{v}-\omega k\right)$
Where $\omega$ is the angular frequency, $v$ is linear velocity? X is distance then dimension formula for $( k )$ is :
  • A
    $[ L\ T]$
  • $[ T ]$
  • C
    $\left[ T ^{-1}\right]$
  • D
    $\left[ T ^2\right]$

Answer

Correct option: B.
$[ T ]$
(B) $[ T ]$,
$\omega K$ should be dimension less
$[ K ]=[\omega]^{-1}=[ T ]$
