$ y = a\cos (\omega t - kx) $ સૂત્રમાં $k$ નું પારિમાણીક સૂત્ર શું થશે?

A

$ [{M^0}{L^{ - 1}}{T^{ - 1}}] $

B

$ [{M^0}L{T^{ - 1}}] $

C

$ [{M^0}{L^{ - 1}}{T^0}] $

D

$ [{M^0}LT] $

Solution

(c) $[Kx]$= Dimension of $\omega t = $ (dimensionless)

hence $K = \frac{1}{X} = \frac{1}{L} = \left[ {{L^{ – 1}}} \right]$

$[K] = [{L^{ – 1}}]$
