Choose an option
Show full solutionCorrect option: A
Correct answer
AThe dimensions of is [T]
Step-by-step explanation
Comparing the given equation with standard equation of standing
$\begin{aligned}
& {\left[\frac{\mathrm{n}}{\lambda}\right]=[\omega]=\mathrm{T}^{-1}} \\
& {[\mathrm{nt}]=[\lambda]=\mathrm{L}} \\
& {[\mathrm{n}]=[\lambda \omega]=\mathrm{LT}^{-1}} \\
& {[\mathrm{x}]=[\lambda]=\mathrm{L}}
\end{aligned}$
