Question

the wavelength associated with a moving electton depends on its mass, its velocity and Plancks constant, prove dimensionalaly that wavelight proportional to h/ mv
​

Answer 1

Answer:

Explanation:

dimension of h= M L^2 T^-1

dimension of m=M

dimension of v= L T^-1

dimension of WAVELENGTH= L

now   L=ML^2T-1/MLT^-1

          L=L

        L.H.S=R.H.S
