What is the gas constant in SI units?
Joules/K.mol
What is Planck's constant dimensionally equal to?
Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.
What are the units of h in the equation E equals hf?
E is energy in Joules (J) or Electron Volts (eV). h is Planck's Constant. When using joules, Planck's constant is 6.63*10^-34 Joule*seconds (J*s). When using electron volts, Planck's constant is 4.14*10^-15 electron volt*seconds (eV*s). f is the frequency of light in inverse seconds or 1/second
What is the base unit of Plancks constant?
Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.
What is Planck constant value?
Planck's constant was originally defined as the constant of proportionality in the relationship between the energy, E, of a charged atomic oscillator in a black body, and the frequency, ν, of its associated radiation. It is now defined, equivalently, as the quantum of action in quantum physics. Its value is 6.626*10^(-34) Joules seconds.
