The relation between the energy $E$ and the frequency $v$ of a photon is expressed by the equation $E = h v$ , where $h$ is Planck's constant. Write down the SI units of $h$ and its dimensions.

Options:

Answer:

Solution:

$h = \frac{E}{ν}$
$= \frac{J}{s ^{- 1}}$
$= J - s; [h]$
$= [M L^{2} T^{- 2}] [T]$
$= [M L^{2} T^{- 1}]$ .
