what is the dimension of planks constant
what is dimnsion of gravitational constant
plank,s constant
6.626x10-34 m2kg/s is the value of Plank's constant.
The dimension of mass is always [M].
It is m2.
The reduced Planck constant simplifies the mathematics found in quantum physics calculations by adding a 2pi term into it. Instead of worrying about that 2pi constant, formulas using the reduced Plank constant have it built in.
It is the constant of proportionality relating the energy of a photon to the frequency of that photon.Its value is approximately 6.626 × 10-34 joule-second.Its symbol is h
E=hf where f is frequency and h is plank's constant.
E=hv Where: E is energy h is plank's constant and v is frequency.
They are [L^3]*M^-1][T^-2].
The dimensions are [L^3 M^-1 T ^-2].
