If the Iongest Wavelength of Light That Is Able to Dislodge

question 38

Short Answer

If the Iongest wavelength of light that is able to dislodge electrons from a metal is $373 \mathrm {~nm}$ , what is the work function of that metal, in electron-volts? $\left( 1 \mathrm { eV } = 1.60 \times 10 ^ { - 19 } \mathrm {~J} , c = 3.00 \times \right.$ $\left. 10 ^ { 8 } \mathrm {~m} / \mathrm { s } , h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } \right)$
