Question

find the dimensions of placks constant?​

Answer 1

$\huge{\mathfrak{Solution:-}}$

$\sf{By\;using\;E=hv}$

$\sf{Where,}$

$\sf{E=energy}$

$\sf{h=Planck\;constant}$

$\sf{v=frequency}$

$\sf{Energy\;dimension=[ML^{2}T^{-2}]}$

$\sf{Frequency\;dimension=[T^{-1}]}$

$\sf{So,}$

$\sf{E=hv}$

$\sf{[ML^{2}T^{-2}]=h[T^{-1}]}$

$\sf{h=\frac{[ML^{2}T^{-2}]}{[T^{-1}]}}$

${\boxed{\boxed{\red{\sf{h=[ML^{2}T^{-2}]}}}}}$
