1.	Dimension of Planck's constant is(B)ML2T-2ML27-1(D)MLT-2(C)MLT-1
Answer» ANSWER : $[ML^2T^{-1}]$ Planck's constant is given by the formula $\tt Planck's\ constant = \dfrac{energy}{<klux>FREQUENCY</klux>}$ $\tt h = \dfrac{e}{ \nu}$ The dimensions of energy E is $[ML^2T^{-2}]$ and DIMENSION of frequency is $[T^{-1}]$ . Using them in the above formula : $\tt h = \dfrac{[ML^2T^{-2}]}{[T^{-1}]}$ $\tt h = [ML^2T^{-1}]$ _________________________ Planck's constant gives the energy radiated by one QUANTA of photon to the frequency of the radiation . Its value of 6.62 × $10^{-34}$ Js. Its SI unit is Joule second . It was given by Planck hence named after him .
