Vedclass · Answer

(A) $1$. Planck's constant $(h)$: From $E = h
u$, we have $h = E/
u$. The dimensions are $[ML^2T^{-2}] / [T^{-1}] = ML^2T^{-1}$ $(III)$.$2$. Stopping potential $(V_s)$: It is defined as energy per unit charge, $V_s = E/q$. The dimensions are $[ML^2T^{-2}] / [AT] = ML^2T^{-3}A^{-1}$ $(IV)$.$3$. Work function $(\Phi)$: It is the minimum energy required to remove an electron, so it has the dimensions of energy, $ML^2T^{-2}$ $(I)$.$4$. Threshold frequency $(
u_0)$: It is the minimum frequency of incident light, so it has the dimensions of frequency, $T^{-1}$ $(II)$.Therefore, the correct matching is $A-III, B-IV, C-I, D-II$.
