I want to know the answer to the following question:
The value quoted here for the Planck constant is based on a measurement in what year?
All the background I'm provided with is that "In principle, the Planck constant could be determined by examining the spectrum of a black-body radiator or the kinetic energy of photoelectrons, and this is how its value was first calculated in the early twentieth century.". Is that enough to answer the question?
Answer: no
