1.Units, Dimensions and Measurement
easy
The equation of a wave is given by$Y = A\sin \omega \left( {\frac{x}{v} - k} \right)$where $\omega $ is the angular velocity and $v$ is the linear velocity. The dimension of $k$ is
A
$LT$
B
$T$
C
${T^{ - 1}}$
D
${T^2}$
Solution
(b) From the principle of homogenity $\left( {\frac{x}{v}} \right)$ has dimensions of $T$.
