Write dimensional formula for the intensity of radiation

Question

Write dimensional formula for the intensity of radiation (A)  [ ML0 T3 ]  (B)  [ ML0 T - 3 ]  (C)  [ ML2 T - 2 ]  (D)  [ ML2 T - 3 ]

Tardigrade Admin · Accepted Answer

Intensity of radiation is energy flowing per second per unit area, ie [ Intensity ] = ( [ energy ] / [ time ] [ area ] ) = ( [ ML2 T - 2 ] / [ T ] [ L2 ] ) = [ ML0 T - 3 ]

Q. Write dimensional formula for the intensity of radiation

$[M L^{0} T^{3}]$

$[M L^{0} T^{- 3}]$

$[M L^{2} T^{- 2}]$

$[M L^{2} T^{- 3}]$

Intensity of radiation is energy flowing per second per unit area, ie
[ Intensity ] = $\frac{[ e n er g y ]}{[ t im e ] [ a re a ]}$
= $\frac{[ M L ^{2} T ^{- 2} ]}{[ T ] [ L ^{2} ]}$
= $[M L^{0} T^{- 3}]$

Q. Write dimensional formula for the intensity of radiation

[ML0T3]

[ML0T−3]

[ML2T−2]

[ML2T−3]

Intensity of radiation is energy flowing per second per unit area, ie [ Intensity ] = [time][area][energy]​ = [T][L2][ML2T−2]​ = [ML0T−3]

$[M L^{0} T^{3}]$

$[M L^{0} T^{- 3}]$

$[M L^{2} T^{- 2}]$

$[M L^{2} T^{- 3}]$

Intensity of radiation is energy flowing per second per unit area, ie
[ Intensity ] = $\frac{[ e n er g y ]}{[ t im e ] [ a re a ]}$
= $\frac{[ M L ^{2} T ^{- 2} ]}{[ T ] [ L ^{2} ]}$
= $[M L^{0} T^{- 3}]$
