# The intensity of a wave is defined as the energy transmitted per unit area per second. Which of the following represents the dimensional formula for the intensity of the wave?

${ MT }^{ -3 }$

##### SOLUTION
$\displaystyle I=\frac{E}{A}\times \frac{1}{T}=\left ( M\frac{L^{2}}{T^{2}} \right )\times \frac{1}{L^{2}}\times \frac{1}{T}=MT^{-3}$
Hence, option B is correct.
