Question

Dimensions of
Planck's constant/Thermal diffusivity
are denoted
by
(a) L
(b) M
(c) T
(d)delta​

Answer 1

(a). length

(b). mass

(c). time

Answer 2

Answer:

Energy of photon is given as

E=hν⟹h= νν

Dimension of E=[ML2 T −2 ]

Dimension of ν is [T−1 ]

Thus the dimension of plank's constant h is [ML2T−1 ]
