The dimensions of intensity of wave are

A

`[ L° M T^(–3)]`

B

`[ L^(1) M^(2) T^(–2)]`

C

`[ L^(2) M T^(–2)]`

D

`[ L^(2) M^(2) T^(–3)]`

Text Solution

Verified by Experts

The correct Answer is:
A
Intensity = `("energy")/("area"xx"time")`
`=[(McancelL^(2)T^(-2))/(cancelL^(2)T)]=[MT^(-3)]=[ML^(@)T^(-3)]`
