Photon is quantum of radiation with energy E = hv, where v is frequency and his Planck's constant. The dimensions of h are the same as that of

A

linear impulse

B

angular impulse

C

linear momentum

D

angular momentum

Text Solution

Verified by Experts

For E=hv
`[h]=([E])/([v])=([ML^(2)T^(-2)])/([T^(-1)]=[M^(1)L^(2)T^(-1)]`
For (A), Dimension of linear impulse = Dimension of momentum `[M^(1)L^(1)T^(-1)]`
For (B) and (D),
Dimensions of angular impulse = Dimension of angular momentum =
`[M^(1)L^(-2)T^(-1)]`
This is equal to the dimension of Planck.s constant h.
