Question

The dimensional formula of Planck’s constant h is

      a) [ML2T-1]

      b) [ML2T-3]

      c) [MLT-1]                  

      d) [ML3T-3]

please say to me ​

Answer 1

Answer:

c) MLT-1. hope this will help you out

Answer 2

Answer:

it is [ ML2T-1]

as Energy of photon is given as

E=hν

⟹h=

ν

E

Dimension of E=[ML

T

−2

]

Dimension of ν is [T

−1

]

Thus the dimension of plank's constant h is [ML
