In her physics laboratory, Mathilda shines electromagnetic radiation on a material and collects ...

In her physics laboratory, Mathilda shines electromagnetic radiation on a material and collects photoelectric data to determine Planck's constant. She measures a stopping potential of 5.82 V for radiation of wavelength 100 nm, and 17.99 V for radiation of wavelength 50.0 nm. (1 eV = 1.60 × 10-19 J, c = 3.00 × 108 m/s)
(a) Using Mathilda's data, what value does she determine for Planck's constant?
(b) What is the work function of the material Mathilda is using, in electron-volts?
