The intensity of a traveling wave has units of W//m^(2), give the dimensional formula of intensity :

Answer»

`[ML^(0)T^(-3)]`
`[ML^(1)T^(-2)]`
`[M^(0)L^(-1)T^(2)]`
`[M^(-1)L^(0)T^(-3)]`

SOLUTION :Intensity has units `W//m^(2)`
`:.` E (intensity)=`("Power")/("area")`
`E=(ML^(2)T^(-3))/(L^(2))=ML^(0)T^(-3)`
HENCE CHOICE is `(a)`.
