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.
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.
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
They are [L^3]*M^-1][T^-2].
The dimensions are [L^3 M^-1 T ^-2].
