Find the dimensions of Planck's constant...

Find the dimensions of Planck's constant `h` from the equatioin `E=hv` where `E` is the energy and `v` is the frequency.

Text Solution

Verified by Experts

The correct Answer is:
`ML^(2)T^(-1)`
`E=h v`
`[E]=[h][v]`
`ML^(2)T^(-2)=[h](1)/(T)`
`[h] =ML^(2)T^(-1)`
