why we use h cutt?

[ravaila]

what are the reasons behind using h cutt....as h is the actuall planks contsant ...why scentists feel to use a reduce form of planks constant........?

[mitariq]

Nothing special about h bar , just for mathematical purpose.
just like we know f as frequency but there is omega for angular frequency,
just like lamda the wavelenght, and k the wave number......

[ravaila]

h is for translational and h cutt is for rotational
rite?

i just wanna ask what experiments are responcible to use a reduce plank constant ??

[j87ibz]

one of the examples which uses Reduced_Plank_Constant is to implement mathematical models and simulations of Bohr Magneton .

yup.

h has its significance in physics, because it relates quantum physics to classical physics. h bar is just a mathematical ease, when dealing with plane waves and matter waves.
