Question

If 'h' planck's constant 2 is the wavelength
has the dimensions of
?​

Answer 1

Answer:

The dimension of plancks constant is the same as that of angular momentum. This is one thing which led to the theorem that Bohr orbits are quantized and an integral multiple of nh/ 2*pie. where n is the number of orbits, h is planck’s constant.

Its dimension is ML*L*/T.

M-Mass

L-Lenght

T-Time

You can also do it like

Planck's Constant (h) = Energy(E) / frequency (ν). Putting these values in above equation we get, Dimensional Formula of Planck's constant = M1L2T-1. SI unit of Planck's constant is joule-seconds (j-s).
