Question

The dimensions of Planck's constant are the same as those of angular momentum. Please explain how they are having same dimensions.

Answer 1

hey mate!!

________________________________________________________________

Your answer is...

As, you know planks constant is represented by h

Also,

Lembda= h/p

Where lembda is wavelength

And p is linear momentum=mv

Now,

h = lembda ×mv

h = LM (LT^-)

dimension of planks constant is ML^2T^-

-_________________________

Now,

Angular momentum = mvr

Angular momentum= M(LT^-)L

Dimension of angular momentum is ML^2T^-

Hence,

Dimension of both planks constant And angular momentum is same.

Hope it will help you...
