A scientist in another universe (identical in all respects

Last updated: 7/6/2022

A scientist in another universe (identical in all respects to our own except for the value of Planck's constant), shines electromagnetic radiation of wavelength 2.00 x 10-1 m on a metal with a work function of 9.25 x 10-19 J. Electrons are ejected from the metal, but their maximum kinetic energy is zero. What is the value of Planck's constant as determined from this experiment? 6.63 x 10-34 J.s 2.63 x 10-28 J.s 6.17 x 10-28 J.s 3.57 x 10-28 J.s
