- In A Photoelectric Experiment Using A Platinum Surface You Find A Stopping Potential Of 1 43 V For A Wavelength Of 175 1 (25.92 KiB) Viewed 28 times
In a photoelectric experiment using a Platinum surface, you find a stopping potential of 1.43 V for a wavelength of 175 nm and a stopping potential of 5.62 V for a wavelength of 110 nm. Because this is an experiment, your value of Planck's constant will be slightly different from the official value. From these data find a) a value for Planck's constant h x 10-34J.s b) the work function for Platinum eV I c) the cutoff wavelength for this metal nm
