Question $17(1$ point$)$

An unknown metal has a work function of $3\mathrm{.}5$ eV$.$ What is the stopping potential if the incident light has a wavelength of $185$ nm$?$ Round your answer to the nearest hundredth of V$.$

Take Planck's constant to be h $=6\mathrm{.}626*10-34$ J$$s$,$ the speed of light to be c $=3*108$ m$/$s$,1$eV $=1\mathrm{.}6*10-19$ J$,$ and the mass of an electron to be me $=9\mathrm{.}11*10-31$ kg$=0\mathrm{.}511$MeV$/$c$2$
